PIN DESCRIPTION
Pin no.
Symbol
Descriptions
1
CONTROL
Control signal input pin. Set “H” to turn the switch on, “L” to turn the switch off.
At 0.8 V or less, the chip is in STBY state and current consumption is less
than1
μ
A.
Slow start setting pin. Used to adjust the switch on/off timing.
Add external capacitance to delay operation. Leave open when not in use.
In open mode voltages up to 10 V are present. Care should be taken in mounting
to prevent leak current generation because high impedance is required.
2
SS
3
CURRENT
Current limit setting pin. The limit current level is set by connecting this pin to
external resistance.
If this pin is connected to GND, no current limit is applied.
4
V
IN
Switch input pin.
The V
IN
voltage monitoring function enables switch operation at 1.9 V or higher.
If the V
IN
voltage drops to 1.8 V or lower switch operation is disabled.
5
OUT
Switch output pin.
The discharge function will immediately discharge the capacitance charge
connected to the OUT pin when the switch is in off position and 350
resistance
(with V
CC
= 5 V) is connected to the GND terminal.
6
V
CC
Control power supply input pin. This pin supplies power to the control circuit.
The input voltage level must be stable.
7
GND
Ground pin.
8
O.C
External signal pin.
When the switch is in on mode this pin normally outputs a “H” level signal, but
changes to “L” level when an overcurrent, overheating, or UVLO condition is
detected.
When the switch is in off mode this signal is output at “L” level at all times.
This is an open drain connection, and should be pulled up to high potential using
resistance.
