HV9901

Universal Relay Driver

Features

General Description

The HV9901 universal relay driver provides high-effi-

ciency driving for low-voltage relays with supply volt-

ages as high as 450V. For example, a relay with a 5V

coil can be driven directly from the rectified 120 VAC or

230 VAC line.

• 10V to 450V Input Voltage Range

• Energy-saving Hold Current Mode

• Adjustable Microcontroller Supply

• Low Supply Current <1 mA

• Constant-current Coil Drive

The IC includes two high-voltage linear regulators. The

first one is for providing power to internal control cir-

cuitry. The second one has an adjustable output volt-

age and a 1 mA output current capability to support

external circuitry, such as a microcontroller control cir-

cuit.

• Programmable Pull-in Current, Pull-in Time and

Hold Current

Applications

• Industrial Controls

• Relay Timers

The pull-in current, pull-in time and hold current for the

relay are individually programmable through two resis-

tors and a capacitor. PWM switching can be synchro-

nized with an external clock or with another HV9901

operating at a higher frequency.

• Solenoid Drivers

• Home Automation

The relay is operated through the enable input ENI.

Logic polarity is under control of the polarity input POL.

Audible noise coming from the relay can be sup-

pressed by operating at a PWM frequency exceeding

20 kHz.

Package Type

16-lead SOIC

See Table 2-1 for pin information.

WARNING

The HV9901 is suited for relay driving applications operating at hazardous voltage. Ensure that adequate

safeguards are provided to protect the end user from electrical shock.
