Battery Power Supply. Connect to the positive supply through an external reverse-polarity diode.
Bypassed to GND with a 0.1FF capacitor.
Current Setting Input. Place a 1% resistor (R
threshold range for the DOUT_ outputs. See the Typical Operating Characteristics section for the correct
value of R
parasitic capacitance. See the Input Current Thresholds and Short to Ground section.
Hall-Effect Sensor Input 1. Supplies current to the Hall sensor and monitors the current level drawn to
determine the high/low state of the sensor. Bypass to GND with a 0.01FF capacitor. Connect an unused
input to BAT pin.
Hall-Effect Sensor Input 2. Supplies current to the Hall sensor and monitors the current level drawn to
determine the high/low state of the sensor. Bypass to GND with a 0.01FF capacitor. Connect an unused
input to BAT pin.
