Description

The VN5770AK-E is a device formed by three monolithic chips housed in a standard SO-28 package: a double high side and two low side switches. The double high side is made using STMicroelectronics VIPower™ M0-5 Technology, while the low side switches are fully protected VIPower™ M0-3 OMNIFET II. 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.

Features

■ General features

– Inrush current management by active power limitation on the high side switches

– Very low stand-by current

– Very low electromagnetic susceptibility

– In compliance with the 2002/95/EC European directive

■ Protection

– High side drivers undervoltage shutdown

– Overvoltage clamp

– Output current limitation

– High and low side overtemperature shutdown

– Short circuit protection

– ESD protection

■ Diagnostic functions

– Proportional load current sense

– Thermal shutdown indication on both the high and low side switches

Applications

■ DC motor driving in full or half bridge configuration

■ All types of resistive, inductive and capacitive loads
