IRS2153DSPBF 概要
A gate driver IC (also called a half-bridge driver) is a power-management semiconductor that translates low-power PWM logic signals from a controller into the high-current, high-voltage drive required to switch the gates of MOSFETs or IGBTs in switch-mode power supplies, motor drives, and lighting ballasts. The self-oscillating variant integrates the timing network, removing the need for an external oscillator and simplifying ballast and driver designs.
Key features include a 600V maximum offset voltage, 130 mA / 270 mA typical source/sink gate-drive current, internal deadtime of approximately 1.2 us, low quiescent current, and HVIC + latch-immune CMOS construction for rugged monolithic integration. The IRS2153DSPBF accepts a 10V to 20V VCC supply and includes undervoltage lockout on VCC, with bootstrap capability for the high-side supply.
The IRS2153DSPBF architecture uses a high-voltage level-shifter and latch-immune CMOS logic to drive the high-side channel referenced to the half-bridge switching node (VS). This allows direct connection of the low-side gate return to the system ground while the high-side channel floats with the switching node, eliminating the need for an isolated drive supply in many topologies.
Typical applications include electronic ballast for fluorescent and HID lamps, half-bridge converters, motor driver front ends, and switch-mode power supply drivers. Its self-oscillating nature makes it well suited for cost-sensitive lamp ballast designs where external PWM control is unnecessary. The wide VCC range supports both 12V and 15V system rails commonly found in lighting and industrial subsystems.
When designing with this device, ensure the bootstrap capacitor and diode are correctly sized for the high-side supply, paying attention to refresh pulses during low-side turn-on. The timing resistor (RT) and capacitor (CT) selected on pin 2 set the oscillator frequency - typical fluorescent ballast designs operate in the 30-50 kHz range with appropriate deadtime margins.

主な用途
IRS2153DSPBF の用途: 6 件s: Fluorescent & HID Electronic Ballast, Half-Bridge Switch-Mode Power Supply, Motor Drive Front-End (Low-Voltage BLDC/PMSM), Electronic Transformer for Low-Voltage Halogen Lamps, Auxiliary Power Supply for Industrial Equipment, LED Driver Front-End (AC-DC Stage).
Fluorescent & HID Electronic Ballast
The IRS2153DSPBF's self-oscillating RC network is purpose-built for fluorescent and HID electronic ballasts, where the driver replaces a discrete 555 timer + optocoupler + level shifter with a single 8-SOIC part. Its 600V offset rating directly supports rectified 230V mains with adequate margin, while the ~1.2 us internal deadtime prevents shoot-through in the half-bridge during lamp startup transients. Compared to a discrete implementation, the IRS2153DSPBF reduces BOM count by ~6 components, improves reliability through integrated HVIC latch-immune CMOS, and provides automatic restart via VCC UVLO. Designers typically program the oscillator to 30-50 kHz and add a PTC / thermistor network for lamp preheat.

Half-Bridge Switch-Mode Power Supply
In hard-switched half-bridge converters up to ~500W, the IRS2153DSPBF drives the two primary-side MOSFETs with 130 mA source / 270 mA sink gate-drive current - sufficient for medium-power MOSFETs with Qg up to ~30 nC. The driver's self-oscillating behavior is acceptable for fixed-frequency or open-loop converters (e.g., lamp ballasts, simple chargers), and its 600V rating supports universal-input designs. The 8-SOIC package enables compact PCB layouts where the half-bridge fits beneath the transformer bobbin. For closed-loop control, pair with an external PWM controller on the secondary-side feedback path.

Motor Drive Front-End (Low-Voltage BLDC/PMSM)
The IRS2153DSPBF can drive a half-bridge leg in a low-voltage three-phase BLDC or PMSM motor inverter when combined with external commutation logic. Its 600V rating provides huge headroom for 24V, 48V, and even 400V bus rails, and the 130/270 mA drive current is sufficient for IGBTs and medium-FOM MOSFETs. The 8-SOIC footprint allows placement near each phase leg for minimal gate-loop inductance. Designers should add external shoot-through protection logic and a three-phase controller IC for full three-phase operation - the IRS2153DSPBF is a single half-bridge driver, not a 3-phase pre-driver.
おすすめ
Electronic Transformer for Low-Voltage Halogen Lamps
The IRS2153DSPBF is a near-ideal controller for 12V electronic halogen transformers, where the half-bridge topology at 30-50 kHz replaces the mains-frequency iron-core transformer. The driver's 600V offset handles rectified 230V mains directly, and its self-oscillating behavior eliminates the need for a separate controller IC - reducing total BOM cost in price-sensitive lighting products. The 8-SOIC package and low quiescent current support compact, low-cost PCB layouts that fit inside the lamp base. Output short-circuit protection can be added externally by sensing primary current and pulling the RT/CT pin high.
おすすめ
Auxiliary Power Supply for Industrial Equipment
For auxiliary / standby power supplies in industrial PLCs, motor drives, and HVAC controllers, the IRS2153DSPBF delivers a self-oscillating half-bridge converter at low cost. Its 10-20V VCC range is compatible with standard 12V and 15V auxiliary rails, and the 600V offset rating supports both 230V and 400V industrial mains. The driver's latch-immune CMOS construction provides excellent noise immunity in electrically harsh industrial environments, and the integrated UVLO prevents erratic startup under slow-rising bus voltages. The 8-SOIC package is pin-compatible with the IR2153 family, allowing drop-in modernization of legacy designs.
おすすめ
LED Driver Front-End (AC-DC Stage)
In two-stage AC-DC LED drivers, the IRS2153DSPBF serves as the PFC or front-end half-bridge converter controller, providing an isolated DC bus that feeds a downstream buck or constant-current stage. Its self-oscillating behavior is acceptable for fixed-frequency open-loop front ends, and the 600V rating supports universal-input designs up to ~277V AC. The 130/270 mA gate-drive current can switch MOSFETs up to ~600V / 10A, making it suitable for 50-150W LED luminaires. Designers can disable the oscillator at light load via the RT/CT pin to meet efficiency regulations.

設計ノート
Bootstrap capacitor sizing: choose CBOOT so that VBS remains above the UVLO turn-off threshold during the high-side on-time. A common starting point is CBOOT >= Qg_total / deltaVBS, where deltaVBS is the allowable droop (typically 0.5-1V). For 30 kHz operation with 30 nC Qg MOSFETs and 100 ns high-side on-time, a 100 nF ceramic bootstrap capacitor is usually sufficient. Add a 100 ohm resistor in series with the bootstrap diode to limit inrush current during the low-side refresh pulse.
Minimize the high-side gate-drive loop: place the bootstrap capacitor and diode as close to pins 6 (VS) and 8 (VB) as possible, and keep the gate-drive traces short and wide. The high-side gate return (VS) carries the full switching-node dV/dt - any inductance here couples into the gate drive and can cause spurious turn-on. Use a ground plane on the bottom layer and avoid routing sensitive analog signals (RT/CT) across the switching node.
At low switching frequencies (30-50 kHz) and modest gate-drive currents (130/270 mA), the IRS2153DSPBF dissipates well under 100 mW and requires no heatsink. However, in deadtime-loss-dominated designs or at higher switching frequencies, the gate-drive dissipation PD = Qg * VCC * fSW can become significant - for 30 nC Qg at 100 kHz with 15V VCC, PD = 45 mW per channel. Keep the SOIC-8 ground pad soldered to a continuous ground pour for thermal spreading, even though the thermal pad is not formally specified in all datasheets.
Do not exceed VBS-VS = 20V (the bootstrap supply absolute maximum) - place a 15V Zener or TVS diode across the bootstrap capacitor if there is any risk of over-voltage during start-up or short-circuit events. Also, the RT/CT pin is a sensitive analog node; keep the timing components physically close to pin 2 and use a ground-return trace that does not share copper with switching currents. Finally, verify that VCC rises above the UVLO turn-on threshold (typically 8V) before drawing load current, or the driver may exhibit half-bridge shoot-through.
