What this driver does on the board
The TPS2814P is a low-side gate driver that handles both N-channel and P-channel MOSFETs, with inverting and non-inverting input options on the same chip. It drives two channels synchronously, meaning a pair of FETs in a half-bridge or synchronous rectifier stage can be switched from one driver IC.
Switching speed and drive current
Peak output current is 2 A for both source and sink, with typical rise and fall times of 14 ns and 15 ns respectively. That combination means the gate capacitance of a moderate-power MOSFET charges fast enough to keep switching losses low in a 100–200 kHz converter, without needing an external booster stage. The supply range spans 4 V to 14 V, covering the common 5 V and 12 V gate-drive rails. Logic thresholds are set at 1 V (VIL) and 4 V (VIH), so the inputs are compatible with 5 V logic and most 3.3 V families that swing above 4 V on the high side.
Package and temperature grade
The 8-PDIP footprint is a standard 0.100-inch pitch layout, so it drops into a socket or solders directly into a prototype board without a stencil or reflow profile. The wide range means the driver's timing and drive current stay within spec across a cold start and a hot soak.
