Product details

Half-bridge driver for DC motors and relays — 8.5 A, 160 mOhm

The STMicroelectronics VN5770AK-E is a monolithic half-bridge power MOSFET driver from the OMNIFET II and VIPower families, designed to switch inductive, capacitive, and resistive loads such as DC motors, relays, and general-purpose actuators.

Fault protection and temperature grade

Built-in fault protection includes current limiting, ESD, over-temperature, over-voltage, short-circuit, and under-voltage lockout (UVLO), which reduces the need for external clamp or sense circuits in harsh environments.

Frequently asked questions

What loads can the VN5770AK-E drive?

It is rated for inductive (DC motors, relays), capacitive, and resistive loads, with each half-bridge channel delivering up to 8.5 A continuous.
