V1 (Pin 1): Voltage Input 1. Internal V CC is generated from
the greater voltage on the V1 and V2 inputs. V CC = V1 for
options D1 and E1. Bypass this pin to ground with a 0.1 μ F
(or greater) capacitor.
GND (Pin 2): Ground.
V2 (Pin 3): Voltage Input 2. Internal V CC is generated from
the greater voltage on the V1 and V2 inputs. V CC = V1 for
options D1 and E1. For option A1, B1, C1 bypass this pin
to ground with a 0.1 μ F (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).
TI I G DIAGRA
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-
ageinputisbelowresetthresholdandheldlowfor200ms
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).
