Part number marking
The package is marked with a four letter code in the first line to the
right of the logo. The first three letters designate the product. The
fourth letter, represented by ‘x’, is a date tracking code. The
remaining two or three lines of characters are internal manufacturing
codes.

DESCRIPTION
1
GND
Circuit ground for the device.
2
RESET
Asserted open collector output LOW whenever the V
CC
input source voltage falls below V
S
(4.2 V typical).
The open collector topology requires an external pull-up resistor.
3
CS
Chip select HIGH output signal, asserted whenever the V
CC
input source voltage is above V
S
(4.2 V typical).
Can be used as a chip enable HIGH (CE) signal for system SRAM.
4
V
BATT
CS
Positive polarity connection for lithium back-up battery.
5
Asserted chip select LOW output signal whenever the V
CC
input source voltage is above V
S
(4.2 V typical)
and Y is grounded. Can be used as a chip enable LOW (CE) signal for system SRAM.
6
V
OUT
Primary power with lithium battery back-up power for the protected system. Switch over to lithium battery
back-up operation occurs when V
CC
falls below V
S
.
Open Emitter input to microcontroller used to enable CS output (microcontroller controls CS function).

V
CC
Primary input power source for device.
