Pin number

Pin name

Pin type

Definition

Comments

INTA

Output/digital

Interrupt/fault status/

monitor.

Output pin reports fault via active pulldown interrupt, or reports VCE or VGE

state via logic high/low. Pullup pin to VDD with a 50 kΩ resistor or left open if

unused.

FSSTATE

Input/digital

Fail-safe gate state

control pin.

Gate output control pin. Connect to GND1 if unused. Internal passive

pulldown to GND1.

FSENB

Input/digital

Fail-safe mode enable

pin.

Active-low pin enabling Fail-Safe mode (FSSTATE controls gate). Internal

passive pulldown to GND1. Connect to VDD if unused.

Pins 17 to 32 (high-voltage, isolated pins)

17, 32

GND2

Ground 2

Ground for isolated

(HV) domain power,

analog, and logic.

Redundant GND2 pins provide ground reference for all isolated high-voltage

(HV) domain. Isolated from all circuitry referenced to GND1. Connect to power

device emitter/source.

CLAMP

Input/analog

Sense terminal for

VCE/VDS overvoltage

during turn-off.

CLAMP detects Zener breakdown current and increase gate drive impedance

and employ soft shutdown for turn-off. Connect to VEE if unused.

DESAT

Input-output/

analog

Drive/sense terminal

for VCE/VDS

desaturation condition.

Connected to GND2 if unused.

ISENSE

Input/analog

Current sense

feedback pin.

Resistive network converts current mirror into readable voltage signal on

ISENSE. Connect to GND2 if unused.

21, 23

VEE

Input/power

Negative gate supply

voltage.

VEE is the negative voltage on the isolated domain, and is referenced to

GND2. Connect to GND2 if a negative supply is not used.

Output/analog

Pulldown pin for output

gate turn-off/discharge

event.

GL pin pulls gate to VEE.

AMC

Input-output/

analog

Direct connect to gate

for gate voltage sense

and active Miller clamp

function.

AMC provides low-impedance holdoff (active Miller clamp) and senses VGE/

VGS for reporting and diagnostics.

Output/analog

Pullup pin for output

gate turn-on event.

GH pin pulls gate to VCCREG.

AMUXIN

Input/analog

General-purpose input

for isolated ADC.

One of many SPI-selectable inputs for the isolated ADC. Connect to GND2 if

unused.

VCCREG

Output/power

Internally-regulated

positive gate supply.

Programmable gate supply derived from VCC, referenced to GND2. Connect

to VCC if unused.

VCC

Input/power

Positive voltage supply

for isolated domain

circuitry.

Referenced to GND2.

FSISO

Input/digital

HV domain pin to

enable the Fail-safe

state.

Active-high disables PWM, FSSTATE, and, according to the part number,

turns on gate (MGD3160AM515EK, MGD3160AM315EK, MGD3160

AM518EK or MGD3160AM318EK) or 3-states GATE (MGD3160AM535EK,

MGD3160AM335EK, MGD3160AM538EK or MGD3160AM338EK).

TSENSEA

Input/analog

Anode of temp sense

diode/NTC of the

power module.

TSENSEA reads back voltage from temperature sense element, and is

referenced to GND2. Includes possible current driver for temp sense network.

The temperature sense network cathode should be connected to GND2.

Connect to VREF if unused.

VREF

Output/power

Internally regulated

reference voltage for

HV domain analog,

ADC, and logic.

Output for an internally generated 5.0 V, 20 mA regulator. Referenced to

GND2.
