VN771P
DESCRIPTION
The VN771P is a device formed by three monolithic chips housed in a standard SO28 package: a double high side and two low side switches. Both the double high side and low side switches are made using STMicroelectronics VIPower technology. 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 shut-down to protect the chip from over temperature and short circuit, status output to provide indication for open load in off and on state, overtemperature conditions and stuck-on to VCC. The low side switches are two OMNIFET types (fully autoprotected Power MOSFET in VIPower™ technology). They have built-in thermal shut-down, linear current limitation and overvoltage clamping. Fault feedback for thermal intervention can be detected by monitoring the voltage at the input pin.
