PIN FUNCTION DESCRIPTION
Pin
Function
Description
1
OVLO
The overvoltage shutdown point is programmed by a resistor from this pin to the V
CC
supply. When
tied together with other devices, this pin also communicates a shutdown state due to undervoltage
and overtemperature reasons. All devices connected will simultaneously shutdown. Startup for this
condition may be simultaneous or sequenced.
2
UVLO
A resistor from V
CC
to the UVLO pin adjusts the voltage at which the device will turn on.
3
Enable/Timer
A high level signal on this pin allows the device to begin operation. Connection of a capacitor will
delay turn on for timing purposes. A low input signal inhibits the operation, and communicates to any
other paralleled devices (via the OVLO pin) to shutdown. This signal can also be used to reset the
thermal latch.
4
Ground
Negative input voltage to the device. This is used as the internal reference for the IC.
5
C
charge
An external capacitor is required from this pin to the source pin. This is the storage capacitor for the
internal charge pump. A small internal capacitor is included for noise filtering.
6
I
LIMIT
A resistor (R
LIMIT
) tied from this pin to the source pin sets the current limit level.
7
Power Good
A high impedance signal on this pin indicates that the power device is conducting.

No Connection
10, 11, 12
Source
Source of power FET, which is also the switching node for the load.
13
V
CC
Positive input voltage to the device.
