Power Distribution Controllers

ISL6115, ISL6116, ISL6117,

ISL6120

This family of fully featured hot swap power controllers

targets applications in the +2.5V to +12V range. The

ISL6115 is for +12V control, the ISL6116 for +5V, the

ISL6117 for +3.3V and the ISL6120 for +2.5V control

applications. Each has a hard wired undervoltage (UV)

monitoring and reporting threshold level approximately

80% of the aforementioned voltage.

The ISL6115 has an integrated charge pump allowing

control of up to +16V rails using an external N-Channel

MOSFET whereas the other devices utilize the +12V

bias voltage to fully enhance the N-Channel pass FET.

All ICs feature programmable overcurrent (OC)

detection, current regulation (CR) with time delay to

latch-off and soft-start.

The current regulation level is set by 2 external

resistors; R

ISET

sets the CR Vth and the other is a low

ohmic sense element across, which the CR Vth is

developed. The CR duration is set by an external

capacitor on the CTIM pin, which is charged with a

20µA current once the CR Vth level is reached. If the

voltage on the CTIM capacitor reaches 1.9V the IC then

quickly pulls down the GATE output latching off the

pass FET.

This family although designed for high side switch

control the ISL6116, ISL6117, ISL6120 can also be

used in a low side configuration for control of much

higher voltage potentials.

NOTES:

1. Please refer to TB347

for details on reel specifications. Add “-T” suffix for tape and reel.

2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach

materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both

SnPb and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that

meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

Pin Descriptions

PIN # 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.

3GATEExternal 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

+5V

(ISL6115) and to V

(ISL6116, ISL6117, ISL6120) by a 10µA current source.

4 VSS Chip Return

5 VDD 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

+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 to a maximum of 5V or is left open. Do not drive this input >5V. After a

current limit time-out, the chip is reset by a low level signal applied to this pin. This

input has 20µA pull-up capability.
