PIN FUNCTIONS

LTM2887-S Isolated Side

IVCC2(L7): VCC2 precision current limit adjust pin. Current

limit threshold is set by connecting a resistor between

IVCC2 and GND2. For detailed information on how to set

the current limit resistor value, please see the Applica-

tion Information section. If not used, tie IVCC2 to GND2.

Internally bypassed with 10nF.

VCC2 (L8): 0.6V to 5.5V Adjustable Isolated Supply Volt-

age. Internally generated from VCC by an isolated DC/DC

converterandregulatedto5Vwithnoexternalcomponents.

Internally bypassed with 4.7µF.

I1 (K1): Digital Input, Referenced to VL2 and GND2. Logic

inputconnectedtoDO1throughisolationbarrier.Thelogic

state on I1 translates to the same logic state on DO1. Do

not float.

GND2 (K2 to K5): Isolated Ground.

AVL2 (K6): 5V Nominal Isolated Supply Voltage Adjust.

The adjust pin voltage is 600mV Referenced to GND2. See

Applications Information section for details..

IVL2 (K7): VL2 precision current limit adjust pin. Current

limit threshold is set by connecting a resistor between

IVL2 and GND2. For detailed information on how to set

the current limit resistor value, please see the Applica-

tion Information section. If not used, tie IVL2 to GND2.

Internally bypassed with 10nF.

AVCC2 (K8): 5V Nominal Isolated Supply Voltage Adjust.

The adjust pin voltage is 600mV Referenced to GND2. See

Applications Information section for details.
