IR2153PBF Overview
A half-bridge gate driver is a power-management IC that produces two complementary gate-drive signals (HO and LO) referenced to a switching node (VS) and ground, enabling control of a high-side and low-side power switch in a totem-pole or full-bridge arrangement. The half-bridge driver family belongs to the broader gate-driver IC category, which sits under power management ICs and ultimately under power semiconductors. Compared to low-side-only drivers, half-bridge drivers add a high-voltage level-shifter and bootstrap mechanism that lets the high-side switch be driven when its source sits at the bus voltage. The IR2153PBF extends this with a built-in oscillator, eliminating external PWM generation hardware.
Key features include integrated 600V half-bridge gate driver, 15.6V zener clamp on VCC, micropower startup, tighter initial deadtime control with a low temperature coefficient, shutdown feature (1/6th VCC) on the CT pin, and increased undervoltage lockout (UVLO) thresholds. The internal deadtime and shoot-through protection logic prevent simultaneous conduction of the high-side and low-side MOSFETs. Two output channels source and sink gate charge, producing clean edges on MOSFET gates even at moderate load currents.
Architecturally, the IR2153PBF combines a CMOS 555-style oscillator, an internal bootstrap diode-equivalent level shifter, and high-side / low-side driver buffers rated to 600V. The 15.6V zener clamp on VCC protects the gate driver supply rail from transients, while the micropower startup reduces quiescent current to about 500 uA. The internal deadtime control is tightly toleranced to minimize shoot-through and improve efficiency across operating temperature.
Typical applications include fluorescent lamp ballasts, HID ballasts, switch-mode power supplies (SMPS), motor drivers for small brushless DC fans and pumps, electronic transformers for halogen lighting, and other low-power half-bridge converter topologies. The wide VCC range (10V to 15.6V clamped) makes it compatible with standard 12V and 15V auxiliary rails.
When designing with the IR2153PBF, place RT and CT close to the IC pins to minimize timing jitter, and use a low-ESR bypass capacitor on VCC. The bootstrap diode and capacitor values must be sized for the maximum high-side on-time to avoid UVLO triggering; Infineon recommends a fast-recovery bootstrap diode for high-frequency operation.

Typical Applications
IR2153PBF is suitable for 6 applications: Fluorescent and HID Lamp Ballasts, Switch-Mode Power Supply (SMPS) Half-Bridge, Small Brushless DC Motor Drivers, Electronic Transformer for Halogen Lighting, Induction Heating Cooktop Half-Bridge, UPS and Inverter Auxiliary Stage.
Fluorescent and HID Lamp Ballasts
The IR2153PBF's 600 V high-side rating and integrated RC oscillator make it a textbook choice for self-oscillating fluorescent and HID electronic ballasts. Designers connect RT and CT to set the resonant frequency (typically 30-80 kHz) that drives an LC tank with the lamp load. The integrated 15.6 V VCC clamp eliminates the auxiliary 15 V regulator, while micropower startup at 500 uA lets a simple high-impedance resistor network charge VCC directly from the rectified mains, reducing BOM cost by 8-12 parts versus discrete designs.
Recommended
Switch-Mode Power Supply (SMPS) Half-Bridge
In low- to medium-power SMPS, the IR2153PBF drives a high-side and low-side MOSFET half-bridge with 45 ns rise and 80 ns fall times, supporting switching frequencies up to approximately 100 kHz. The 600 V rating handles universal-mains-derived 400 V bus voltages with margin. The internal deadtime (tight tolerance, low temperature coefficient) prevents shoot-through losses that would otherwise erode efficiency. Designers use it in conjunction with an external PFC stage and synchronous-rectifier controllers for sub-300 W offline converters where a self-oscillating topology is acceptable.
Recommended
Small Brushless DC Motor Drivers
For sub-100 W BLDC fans, pumps, and appliance motors, the IR2153PBF provides the half-bridge drive stage without requiring an external MCU or PWM controller. Its 600 V rating comfortably covers 48-310 V DC bus voltages, while the 8-DIP package fits into compact motor-control PCBs. The shutdown input (1/6 VCC on CT) lets a thermistor or external supervisory circuit disable the driver in fault conditions, and micropower startup at 500 uA is acceptable for always-on standby operation in white goods.
Recommended
Electronic Transformer for Halogen Lighting
The IR2153PBF is widely used in 12V halogen electronic transformers, where 230 VAC mains is rectified and chopped at high frequency (typically 30-50 kHz) before stepping down to 12 V via a small ferrite transformer. Its integrated oscillator eliminates the need for an external PWM controller, the 600 V rating covers rectified mains transients, and the 8-PDIP package handles the through-hole construction preferred for line-voltage safety isolation. The 15.6 V VCC zener clamp also protects against transformer reflected overvoltages.
Recommended
Induction Heating Cooktop Half-Bridge
Low-power induction heating cooktop segments (single-burner sub-2 kW units) use the IR2153PBF in resonant half-bridge topologies with an LC tank driving the induction coil. The 600 V rating and 100 kHz capability are adequate for the 20-50 kHz resonant frequencies typical of these designs. The integrated deadtime control and UVLO improve reliability against the harsh thermal and electrical environment of induction heating, while the 8-DIP package supports through-hole service-friendly construction.
Recommended
UPS and Inverter Auxiliary Stage
In uninterruptible power supplies and small solar inverters, the IR2153PBF drives the auxiliary half-bridge stage that generates housekeeping supplies or low-power inverter outputs. Its 600 V rating handles 400 V bus systems typical of European solar PV strings, and micropower startup allows the driver to be powered from a high-value startup resistor until the auxiliary supply comes online. The shutdown input (1/6 VCC) enables easy integration with the system's supervisory microcontroller for emergency shutdown sequencing.

Key Differentiators
- Integrated CMOS 555-style RC oscillator eliminates external PWM controller (vs IR2104PBF)
- Tighter initial deadtime tolerance with low temperature coefficient (vs IR2151PBF)
- Micropower startup at approximately 500 uA quiescent current (vs IR2155PBF)
Design Notes
Place the RT and CT timing components as close as possible to pins 2 and 3 of the IR2153PBF to minimize stray capacitance that distorts the oscillator waveform. Keep the high-side loop (VB - HO - VS - COM) short and tight to limit high-frequency ringing. Use a low-ESR ceramic bypass capacitor of at least 0.1 uF directly on VCC (pin 1) and a separate bootstrap capacitor of 0.1-1 uF between VB (pin 8) and VS (pin 6), selected for the switching frequency and high-side on-time per the Infineon datasheet.
A common mistake is sizing the bootstrap capacitor too small, which causes VB voltage droop and triggers the high-side UVLO during long high-side on-times. Calculate the bootstrap capacitor using C >= Qg / dV where Qg is the high-side MOSFET total gate charge and dV is the allowable droop (typically 0.5-1 V below VCC). For continuous high-side conduction, add a bootstrap refresh circuit or use a different topology. Do not omit the bootstrap diode - the IR2153PBF does NOT include an internal bootstrap diode in the basic 8-DIP version.
The IR2153PBF in 8-PDIP has moderate thermal dissipation capability; at high switching frequencies (above 80 kHz) with large gate-charge MOSFETs, internal power dissipation can rise significantly. Ensure junction temperature stays below 125C by using the formula Tj = Ta + Pd * theta_JA, where theta_JA for 8-PDIP is approximately 80-100 C/W on a standard JEDEC test board. If the design approaches 100 mW of internal dissipation, consider the IR2153S in SOIC with copper pour or migrating to the IRS2153D which has improved thermal characteristics.
