Pin Description
ON Input. An active-low turns on the device, enabling LDO1, RESET, the ON/OFF logic, and the
serial interface.
ON

Output 2, Output of Linear Regulator 2; 150mA (max) Output Current. Connect a 2.2μF ceramic
bypass capacitor to PGND.
OUT2

Supply Inputs 2 and 3. Voltage supply for linear regulators 2 and 3.
IN2/3
18
Output 3, Output of Linear Regulator 3; 150mA (max) Output Current. Connect a 2.2μF ceramic
bypass capacitor to PGND.
OUT3
17
Supply Input 1. Voltage supply for linear regulator 1 and serial interface.
IN1
16
Output 1, Output of Linear Regulator 1; 300mA (max) Output Current. Connect a 4.7μF ceramic
bypass capacitor to PGND.
OUT1
15
Output 4, Output of Linear Regulator 4; 150mA (max) Output Current. Connect a 2.2μF ceramic
bypass capacitor to PGND.
OUT4
14
Supply Inputs 4 and 5. Voltage supply for linear regulators 4 and 5.
IN4/5
13
Output 5, Output of Linear Regulator 5; 150mA (max) Output Current. Connect a 2.2μF ceramic
bypass capacitor to PGND.
OUT5
12
OFF Input. A low level to this pin when
ON
is high turns off the IC once the watchdog timer has
timed out. A high-level input keeps the chip on. There is an internal 155k
pulldown resistor at
this input.
OFF

Open-Drain Driver Output 2. Maximum sink current is 150mA (100mA
RMS
). Can drive up to
10 LEDs for backlight or a vibrator motor.
DR2

). Can drive up to
10 LEDs for backlight or a vibrator motor.
DR1
9
Ground
GND
5
Reset Output. Holds the μC system reset line low during initial startup and whenever OUT1 falls
out of regulation.
RSO
has a 140ms (min) timeout period and is an open-drain output with an
internal 14k
pullup to OUT1. The
RSO
line maintains a valid low output level for IN1 as low
as 1V.
RSO

Power Ground
PGND

1.25V Reference Bypass. Connect a 0.01μF bypass capacitor to GND for reduced noise.
Do not load this pin.
BP
6
ON Output. Indicates the state of
ON
. After initial power-up, the logic level of this pin follows that
of
ON
. Used to signal the microcontroller (μC) for an OFF request (allows push-on/push-off).
ONO
