Product details

What the 2A peak output buys you in a switching loop

The TPS2812D delivers 2 A peak source and 2 A peak sink current, which means it charges and discharges the MOSFET gate capacitance fast enough to keep switching losses under control at moderate frequencies. For a typical power MOSFET with 10 nC total gate charge at Vgs=10 V, the driver's 14 ns rise and 15 ns fall times translate to a gate-drive current of roughly 0.7 A average during the switching transition — well within the 2 A peak headroom, so the actual switching speed is set by the gate resistor and the Miller plateau, not by the driver's current limit.

Low-side config and synchronous channel pairing

This is a low-side driver — the output switches the MOSFET source to ground, so it is the right choice for the bottom FET in a half-bridge or for driving a single N-channel in a buck converter. The two channels are synchronous, meaning both outputs switch together; that suits applications where two paralleled FETs share the load or where a push-pull stage needs matched timing. For a half-bridge with a high-side FET, you would pair this with a separate bootstrap or isolated high-side driver.

Supply and logic interface — what the thresholds mean

The supply range is 4 V to 14 V, covering the common 5 V and 12 V gate-drive rails. The logic input thresholds — 1 V for VIL and 4 V for VIH — are compatible with 5 V logic from a microcontroller or PWM controller, but a 3.3 V logic output will not reliably reach the 4 V VIH threshold; a level shifter or open-drain buffer with a pull-up to the driver supply is needed in that case.

Temperature grade and package — board-fit reality

The supplier device package is listed as 8-SOIC, confirming the same mechanical outline.

Frequently asked questions

What gate types does the TPS2812D drive?

The TPS2812D drives both N-Channel and P-Channel MOSFETs. The low-side configuration means the source of an N-channel FET connects to ground, while for a P-channel the driver pulls the gate low to turn it on.
