V1 (Pin 1): Voltage Input 1. Internal V
the greater voltage on the V1 and V2 inputs. V
options D1 and E1. Bypass this pin to ground with a 0.1µF
(or greater) capacitor.
GND (Pin 2): Ground.
V2 (Pin 3): Voltage Input 2. Internal V
the greater voltage on the V1 and V2 inputs. V
options D1 and E1. For option A1, B1, C1 bypass this pin
to ground with a 0.1µF (or greater) capacitor. V2 is an
adjustable input for options D1 and E1. See Table 1b for
recommended ADJ resistor values.
V3 (Pin 4): Voltage Input 3. This input assists the RST pull-
down circuitry below 1V (for options A1, B1 and C1 only).

V3 is an adjustable input for options D1 and E1. See Table
1b for recommended ADJ resistor values.
V4 (Pin 5): Voltage Input 4. Table 1 lists the recommended
ADJ resistor values for options A1, B1 and C1. See Table
1b for options D1 and E1.
RST (Pin 6): Reset Logic Output. Pulls low when any volt-
age input is below reset threshold and held low for 200ms
after all voltage inputs exceed threshold. The pin contains
a weak pull-up to V2 (V1 for options D1 and E1). Use an
external pull-up for faster rise times or output voltages
greater than V2 (V1 for options D1 and E1).
