Product details

Single low-side gate driver with 3A source, 7A sink

Its 3A peak source and 7A peak sink current capability — paired with 14 ns typical rise and 12 ns typical fall times — delivers the gate charge needed for fast switching in synchronous rectifiers, DC-DC converters, and motor-drive output stages. The input accepts both inverting and non-inverting logic, so a single part covers both polarity requirements from the controller without an external inverter gate.

Supply rail and logic thresholds

Operating supply range runs from 3.5 V to 14 V. The VIL/VIH thresholds are set at 0.8 V and 2.3 V.

Package thermal path — the exposed pad matters

ROHS3 compliant.

Frequently asked questions

What is the peak source and sink current of LM5112MY/NOPB?

Peak output current is 3 A source and 7 A sink. That asymmetric ratio is intentional — the higher sink current pulls the MOSFET gate down faster than it charges it, which helps control the turn-off di/dt and reduces shoot-through margin in half-bridge stages.

Can LM5112MY/NOPB be used with both inverting and non-inverting inputs?

Yes, the input accepts both inverting and non-inverting logic. A single part covers either polarity requirement from the PWM controller without adding an external inverter gate.

What are the alternatives or equivalents for LM5112MY/NOPB?

The closest functional peer in TI's portfolio is the LM5106MM/NOPB, a half-bridge driver with two outputs and 1.2 A switching current. It is not a pin-for-pin substitute — the LM5106 adds a bootstrap diode for high-side drive and changes the package to an 8-MSOP-PowerPad. If you need a single low-side driver, the LM5112MY/NOPB is the correct part; the LM5106 serves a different topology.
