SM74104

High Voltage Half-Bridge Gate Driver with Adaptive Delay

General Description

Features

The SM74104 High Voltage Gate Driver is designed to drive

both the high side and the low side N-Channel MOSFETs in

a synchronous buck configuration. The floating high-side driv-

er is capable of working with supply voltages up to 100V. The

high side and low side gate drivers are controlled from a single

input. Each change in state is controlled in an adaptive man-

ner to prevent shoot-through issues. In addition to the adap-

tive transition timing, an additional delay time can be added,

proportional to an external setting resistor. An integrated high

voltage diode is provided to charge the high side gate drive

bootstrap capacitor. A robust level shifter operates at high

speed while consuming low power and providing clean level

transitions from the control logic to the high side gate driver.

Under-voltage lockout is provided on both the low side and

the high side power rails. This device is available in the stan-

dard SOIC-8 pin and the LLP-10 pin packages.
