Block diagram and pin description

Figure 2. Configuration diagram (top view)

Power limitation

Limits the power dissipation of the high-side driver inside

safe range in case of short to ground condition.

Open-load in OFF-state

Signalize, in combination with an external resistor, an open-

load when the switches are off by a feedback on the

MultiSense

Tchip monitoring

Provides a signal linked to the Chip temperature by a

feedback on the MultiSense

VCC monitoring

Provides a signal linked to the Chip temperature by a

feedback on the MultiSense

Reverse driver

Drives an external PowerMOSFET to provide the reverse

battery protection

Charge pump to drive the external N-MOSFET used on the

battery track for the reverse battery protection.



The N-MOSFET source must be connected to the Vbatt pin.
