VN770K
Quad smart power solid state relay for complete H bridge configurations
Features
Type VN770K RDS(on) 220 m(1) IOUT 9A(2) VCC 36V

1. Total resistance of one side in bridge configuration 2. Typical current limitation value

Suited as low voltage bridge Linear current limitation Very low stand-by power dissipation Short circuit protected Status flag diagnostic (open drain) Integrated clamping circuits Undervoltage protection ESD protection

SO-28

This device is suitable to drive a DC motor in a bridge configuration as well as to be used as a quad switch for any low voltage application. The dual high side switches have built-in thermal shutdown to protect the chips from overtemperature and current limiter blocks to protect the device from short circuit. Status output is provided to indicate open load in off and on state and overtemperature. The low side switches are two OMNIFET II types (fully autoprotected Power MOSFET in VIPowerTM technology). They have built-in thermal shutdown, linear current limitation and overvoltage clamping. Fault feedback for thermal intervention can be detected by monitoring the voltage at the input pin.

Description
The VN770K is a device formed by three monolithic chips housed in a standard SO-28 package: a double high side and two low side switches. Both the double high side and low side switches are made using |STMicroelectronics VIPowerTM M0-3 Technology.
