Pin Descriptions

SYMBOL
FUNCTION
DESCRIPTION
1
ISET
Current Set
Connect to the low side of the current sense resistor through the current limiting set resistor. This
pin functions as the current limit programming pin.
2
ISEN
Current Sense
Connect to the more positive end of sense resistor to measure the voltage drop across this
resistor.
3
GATE
External FET Gate Drive
Pin
Connect to the gate of the external N-Channel MOSFET. A capacitor from this node to ground
sets the turn-on ramp. At turn-on this capacitor will be charged to V
DD
+5V (ISL6115) and to
V
DD
(ISL6116, ISL6117, ISL6120) by a 10
μ
A current source.

5
V
DD
Chip Supply
12V chip supply. This can be either connected directly to the +12V rail supplying the switched
load voltage or to a dedicated V
SS
+12V supply.
6
CTIM
Current Limit Timing
Capacitor
Connect a capacitor from this pin to ground. This capacitor determines the time delay
between an overcurrent event and chip output shutdown (current limit time-out). The duration
of current limit time-out is equal to 93k
x C
TIM
.
7
PGOOD
Power Good Indicator
Indicates that the voltage on the ISEN pin is satisfactory. PGOOD is driven by an open drain
N-Channel MOSFET and is pulled low when the output voltage (VISEN) is less than the UV
level for the particular IC.
8
PWRON
Power ON
PWRON is used to control and reset the chip. The chip is enabled when PWRON pin is driven
high or is open. After a current limit time out, the chip is reset by a low level signal applied to
this pin. This input has 20
μ
A pull up capability.
