PIN FUNCTIONS
V1 (Pin 1/Pin 4): Voltage Input 1. V1 is the internal V
The operating voltage on this pin shall not exceed 6V.
When in normal operation, this pin draws approximately
22μA. Bypass this pin to ground with a 0.1μF (or greater)
capacitor.
V
for recommended ADJ resistors values.
RST (Pin 3/Pin 4): Reset Logic Output. Pulls low when
any voltage input is below the reset threshold and is held
low for 200ms after all voltage inputs are above threshold.
This pin has a weak pull-up to V
