Product details

4 A peak drive, 17 ns edges — half-bridge MOSFET driver for harsh environments

This drive strength is sized for switching large MOSFETs in synchronous rectifier stages, DC-DC converters, and full-bridge topologies where fast gate charging directly reduces switching losses. The supply range spans 3.7 V to 20 V. The driver operates over a -55°C to 115°C junction temperature range.

Inverting input logic with synchronous channel configuration

The input type is inverting, and the two channels operate in synchronous mode — the lower driver's state is derived from the upper driver's input with built-in dead-time management.

Buyers should expect to work with broker-vetted stock; the part is not available through factory-authorized channels.
