Connect a 0.01-μF 100-V capacitor between CP1 and CP2.
Connect to system ground
Bypass to GND with a 0.47-μF 6.3-V ceramic capacitor. Use
for suppling external loads is permissible.
Connect a 0.1-μF 16-V ceramic capacitor to VM.
Connect to power supply (8.2 V–60 V). Connect both pins to
the same supply. Bypass to GND with a 10-µF (minimum)
capacitor.
Logic high enables OUT1. Internal pulldown
Logic high enables OUT2. Internal pulldown
Logic high enables OUT3. Internal pulldown
Logic input controls state of OUT1. Internal pulldown
Logic input controls state of OUT2. Internal pulldown
Logic input controls state of OUT3. Internal pulldown
Active-low reset input initializes internal logic and disables the
outputs. Internal pulldown
Logic high to enable device, logic low to enter low-power sleep
mode. Internal pulldown
Logic low when in fault condition (overtemperature,
overcurrent, UVLO)
Negative input of comparator
Positive input of comparator
Output of comparator. Open-drain output
