Power Ground Pin

Wake-up Input

This pin must not be connected or connected to ground.

This pin is the device low side ground connection. It is internally connected to

the LGND pin.

This pin is the wake-up capable digital input(1). In addition, L1 input can be

sensed analog via the analog multiplexer.

AGND

Analog Ground Pin This pin is the device analog ground connection.

Notes

1. When used as digital input, a series 33 kΩ resistor must be used to protect against automotive transients.

2. Reverse battery protection series diodes must be used externally to protect the internal circuitry.

3. This pin can be connected directly to the battery line for voltage measurements. The pin is self protected against reverse battery

connections. It is strongly recommended to connect a 10 kΩ resistor in series with this pin for protection purposes.

4. External capacitor (1.0 µF < C < 10 µF; 0.1 Ω < ESR < 5.0 Ω) required.

5. External capacitor (2.0 µF < C < 100 µF; 0.1 Ω < ESR < 10 Ω) required.
