Typical Applications
IRS10752LTRPBF is suitable for 6 applications: 48V Telecom Isolated DC-DC Converter, Automotive 12V High-Side Load Switch, LED Lighting Driver High-Side Switch, Industrial Auxiliary Power Supply, Solenoid and Relay Driver Module, Battery Management Isolation Switch.
48V Telecom Isolated DC-DC Converter
The IRS10752LTRPBF is well suited as the high-side primary switch driver in 48V telecom isolated DC-DC converters. Its 100V blocking voltage comfortably exceeds the 48V nominal plus 75V transient envelope of the ETSI/NEBS telecom bus. With 0.16A source / 0.24A sink drive strength it can switch a small primary-side MOSFET at frequencies up to 100kHz, enabling compact flyback or active-clamp forward topologies. The integrated 100V level-shift cell eliminates the bootstrap diode and refresh capacitor needed by half-bridge drivers, allowing 100% duty-cycle operation when required for soft-start profiles. Place the VCC bypass within 3mm of pin 5 and keep the VB-VS loop area below 5mm squared to limit ringing.
Recommended
Automotive 12V High-Side Load Switch
For automotive 12V high-side load switches such as lamp drivers, solenoid pre-drivers, and small DC motor relays, the IRS10752LTRPBF offers a logic-level PWM input and integrated 100V transient protection. The non-inverting input with internal pull-down guarantees the FET stays off during microcontroller reset, meeting automotive functional-safety expectations. Its 0.24A sink current handles Miller-induced turn-off spikes in 60V-rated MOSFETs, while the small PG-SOT23-6 footprint fits behind the connector in space-constrained Body Control Modules. Add a TVS clamp and 100kHz low-pass RC at the gate to manage ISO 7637-2 transient pulses.
Recommended
LED Lighting Driver High-Side Switch
In constant-current LED drivers that require a high-side disconnect switch for PWM dimming, the IRS10752LTRPBF can drive a 100V P-channel or upper N-channel MOSFET to break the LED string current. The 0.16A source current supports PWM dimming ratios up to 1000:1 at 1kHz, while the wide 10-20V VCC range simplifies power from either 12V or 15V aux rails. For dim-to-off applications, the driver's low propagation delay ensures consistent dimming linearity across the full duty cycle. The PG-SOT23-6 package sits comfortably in the driver section of commercial LED luminaires and emergency lighting modules.
Recommended
Industrial Auxiliary Power Supply
The IRS10752LTRPBF is a strong fit for auxiliary 24V/48V power rails in industrial PLCs, sensors, and HMIs where a small high-side switch or low-power buck converter is needed. Its 100V rating tolerates the 60V industrial transient envelope and the 100V DC test pulse. With 0.24A sink current, the IRS10752L drives 80-100V MOSFETs directly, replacing a P-channel FET that would otherwise introduce a 1V drop and efficiency loss. Its -40C to +125C operating range covers factory floor and outdoor cabinet environments without derating.
Recommended
Solenoid and Relay Driver Module
For driving small DC solenoids, relays, or proportional valves in industrial and white-goods applications, the IRS10752LTRPBF provides a logic-controlled high-side switch with 0.24A sink and 0.16A source drive. This is enough to switch 24V coils at currents up to 1A when paired with an appropriate logic-level N-FET. The integrated 100V blocking provides headroom against the inductive kick-back of 24V coils, and the small PG-SOT23-6 footprint allows high-density relay banks on the PCB. Use an external flyback diode or TVS for inductive loads, sized at 1.5x the coil voltage.
Recommended
Battery Management Isolation Switch
In multi-cell battery management systems (BMS) for e-bikes, power tools, and portable energy storage, the IRS10752LTRPBF serves as the high-side isolation switch driver. Its 100V blocking rating covers 14S/16S Li-ion stacks (nominally 48V/58.8V full charge) with margin, while the 10-20V VCC range simplifies bootstrap from a 12V auxiliary rail. The integrated level shift removes the need for an isolated DC-DC, saving BOM cost in cost-sensitive consumer battery packs. With low propagation delay, the IRS10752L enables fast short-circuit shutoff under BMS fault conditions, protecting downstream MOSFETs and the battery cells.

Key Differentiators
- Integrated 100V blocking eliminates bootstrap diode and refresh capacitor (vs IRS2003 (half-bridge driver))
- 100V offset voltage in PG-SOT23-6 is the smallest footprint at this rating (vs BSP75G (60V Smart High-Side Switch in PG-SOT23-6))
- Higher sink current (0.24A) handles Miller turn-off spikes in IGBTs (vs IRS10751LTRPBF (0.18A sink, same package))
Design Notes
Keep the high-voltage VB-VS loop area below 5mm squared to limit parasitic inductance and ringing on the gate drive. Place a 100nF X7R ceramic bypass capacitor within 3mm of the VCC pin and a second 10nF-100nF across the VB-VS supply. Route the IN logic trace away from the high-voltage traces to avoid capacitive coupling; if it must cross, cross at 90 degrees.
Estimated: at 100kHz switching into a 10nC gate load, gate-drive loss is approximately P = Qg * Vgs * fsw = 10nC * 12V * 100kHz = 12mW per channel. The PG-SOT23-6 has theta_JA around 250 C/W, so junction temperature rise is only 3C at room temperature. Thermal management is generally not a concern at typical gate-charge levels, but at 1MHz switching and high gate charge, monitor the exposed pad temperature.
Do not exceed the 100V VB-VS rating - even a 100V transient from a 48V automotive load-dump event can exceed the absolute maximum. Add a TVS clamp (e.g., 90V SMBJ) across VB-VS in 48V automotive applications. Also note that the IRS10752LTRPBF does NOT include dead-time control, so it is not a drop-in for half-bridge drivers like the IRS2003. Always confirm the package pinout matches the datasheet, as some SOT-23-6 high-side switches use a different pinout (e.g., pin 1 = GND vs IN).
Compliance Information
