VNH7040AY

Block diagram and pin description

MultiSense

Multiplexed Analog Signal. It delivers a current proportional to the load or a

voltage proportional to the VCC voltage or a voltage proportional to the chip

temperature whenever the MultiSense_EN is set to high. The desired signal is

chosen via SEL0 and SEL1 levels. The MultiSense pin supplies as well a Fault

Flag when a fault is detected on the selected path A or B.

MultiSense_EN

Active high compatible with 3 V and 5 V CMOS output pin. It enables the

MultiSense diagnostic pin.

1. If the device is used in Bridge configuration we indicate: Source_HSDA = Drain_LSDA = OUTA;

Source HSDB = Drain LSDB = OUTB; OUTA and OUTB are the power connections to the motor.
