NOTES:

1. Add “-T” suffix for tape and reel. Please refer to TB347 for details on reel specifications.

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.

3. For Moisture Sensitivity Level (MSL), please see device information page for ISL95813. For more information on MSL, please see tech brief TB363.

Pin Descriptions

NAME

FUNCTION

1

VR_ON

Digital Input Enable input for controller. Connect to ground to disable the part. Connect to VCC to initiate

soft-start and regulation.

2

PGOOD

Digital Output Power-Good open-drain output indicating when VR is in regulation with no faults detected. Pull up

externally with a 680Ω resistor to VCCP or 1.9kΩ to 3.3V.

3

IMON

Analog Output: VR output current monitor. IMON pin sources a current proportional to the regulator output current.

[Small-signal] A resistor connected from this pin to ground will set a voltage that is proportional to the load

current. This voltage is sampled with an internal ADC to produce a digital IMON signal that can be

read through the serial communications bus.

4

VRHOT#

Digital Output Open drain thermal overload output indicator. Can be considered part of communication bus with

CPU.

5

NTC

Analog Input: Thermistor input to VR_HOT# circuit. Used to monitor VR temperature.

[Small-Signal]

6

COMP

Analog Output: Output of the gm error-amplifier for loop control. Connect to ground through the compensation

[Small-signal] network.
