Preliminary

Universal Relay Driver

General Description

Features

The Supertex HV9901 is a BiCMOS/DMOS universal relay

driver that employs PWM switching techniques. It is designed for

efficient and energy-saving operation of a low voltage relay with

supply voltages ranging from 8 to 450V DC through utilization of

the relay coils’ inductance.

❐ 8V to 450V Input Voltage Range

❐ Energy Saving Hold Current Mode

❐ Adjustable Microcontroller Supply

❐ Low Supply Current <1mA

❐ Constant Current Coil Drive

The circuit is capable of operating over a wide input voltage

range without requiring a change of any external components.

For example, this will enable users to use 5V coil relays for DC

voltages 8 - 450V or AC voltages up to 240V.

❐ Programmable Pull-in Current, Pull-in Time, and Hold

Current

The HV9901 has an internal high-voltage regulator to power

internal PWM circuitry. Additionally it includes an adjustable

auxiliary regulator with a 1mA capability that can be used to

supply low power microcontrollers.

❐ Efficient PWM Operation Using the Relay Coils’ Inductance

The pull-in current, pull-in time and hold current are all program-

mable using only two resistors and a capacitor. The PWM

switching frequency can be either

frequency is the highest free-running frequency

The enable (ENI) logic input is used to turn the relay on/off.

Enable polarity may be selected via the POLinput.Audible noise

is prevented using fixed switching frequencies above 20kHz.

❐ Solenoid Drivers

❐ Home Automation

WARNING!!! Galvanic isolation is not provided. Dangerous voltages are

present when connected to theAC line. It is the responsibility of the designer

to ensure adequate safeguards are in place to protect the end user from

electrical shock.
