ILC6360 1.1

Pin Number

Pin Name

Pin Description

1

Inductor input. Inductor L connected between this pin and the battery

2

Connect directly to battery

3

LBI/SD

Low battery detect input and shutdown. Low battery detect threshold is set with this pin

using a potential divider. If this pin is pulled to logic low then the device will shutdown.

4

SYNC

this pin will over-ride the internal 300kHz oscillator. If the SYNC function is unused, pin

4 should be connected to ground

5

POK

(ILC6382CIR-XX)

This open drain output pin will go high when output voltage is within regulation,

(ILC6382CIR-ADJ)

This pin sets the adjustable output voltage via an external resistor divider network. The

formula for choosing the resistors is shown in the “Applications Information“ section.

6

LBO

This open drain output will go low if the battery voltage is below the low battery

threshold set at pin 3

7

GND

Connect this pin to the battery and system ground

8

This is the regulated output voltage
