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.
