V2 (Pin 1/Pin 4): Voltage Input 2. The greater of V1, V2 is
also the internal VCC. The operating voltage on this pin
shall not exceed 6V. When in normal operation (V1 > V2),
this pin draws approximately 8
A. When this pin is acting
as the VCC (V2 > V1), this pin draws an additional 15A.
Bypass this pin to ground with a 0.1
F (or greater)
capacitor.
V4 (Pin 2/Pin 3): Voltage Input 4.
RST (Pin 3/Pin 2): 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 VCC and may be pulled above VCC
using an external pull-up.
GND (Pin 4/Pin 1): Device Ground.
(TS8 Package/DDB8 Package)
VADJ2 (Pin 5/Pin 8): Adjustable Voltage Input 2. See
Table 1 for recommended ADJ resistors values.
V3 (Pin 6/Pin 7): Voltage Input 3.
VADJ1 (Pin 7/Pin 6): Adjustable Voltage Input 1. See
Table 1 for recommended ADJ resistors values.
V1 (Pin 8/Pin 5): Voltage Input 1. The greater of V1, V2 is
also the internal VCC. The operating voltage on this pin
shall not exceed 6V. When in normal operation (V1 > V2),
this pin draws approximately 21
A. When this pin is not
acting as the VCC (V2 > V1), this pin draws approximately
8
A. Bypass this pin to ground with a 0.1F (or greater)
capacitor.
Exposed Pad (Pin 9, DDB8 Only): Exposed Pad may be left
open or connected to device ground.
