PIN FUNCTIONS

Name

Functions

INT

A Capacitor Connected Between this Pin and OutG Defines the GATE

Voltage Slew Rate.

Analog Input Controlling the PWM Ratio. The operating range of the input

voltage is 0 to VR.

3VR

Output of an Internal Voltage Reference

TTL Compatible Input for Switching off the Output.

PWL

If this Pin is Connected to GND and VS > 13 V, the Duty Cycle and the

Frequency fo are Reduced : this Allows to Transfer a Costant Power to the

Load.

Osc

Current Sink and Source Stage Connection of a Triangle Oscillator with

Definite Voltage Swing.

IND

Input of an Operational Amplifier for Short Current Sensing and Regulation.

Not Connected.

9VS

Common Supply Voltage Input

GND

Common Ground Connection

TIM

A Capacitor Connected Between this Pin and GND Defines the Protection

Delay Time.

MON

Open Collector Monitoring Output off the PowerMOS Protection.

13,15

P2, P1

Connection for the Charge Pump Capacitor.

The Capacitor Connected Between thisPin and theSource of the Power MOS

Allows to Bootstrap the Gate Driving Voltage.

Out G

Output for Driving the Gate of the External PowerMOS.
