DESCRIPTION

The VND810 is a monolithic device designe d in STMicroelectronics VIPower M0-3 Technology, intended for driving any kind of load with one side connected to ground. Active VCC pin voltag e clamp protects th e dev ice against low energy spikes (see ISO7637 transient compatibility table). Active current limitation

combined with thermal shutdown and automatic restart protects the device against overloa d. The device detects open load condition both in on and off state. Output shorted to VCC is detected in the off state. Dev ice auto mati cally tur ns off in c ase of ground pin disconnection.
