Universal Relay Driver
General Description
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
10 to 450V DC through utilization of the relay coils’ inductance.
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 5.0V coil relays for DC voltages 10 to 450V or AC
voltages up to 240V.
The HV9901 has an internal high-voltage regulator to power internal
PWM circuitry. Additionally, it includes an adjustable auxiliary regulator
with a 1.0mA capability that can be used to supply low power micro
controllers.
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:
The enable (ENI) logic input is used to turn the relay on/off. Enable
polarity may be selected via the POL input. Audible noise is prevented
using fixed switching frequencies above 20kHz.
WARNING!!! Galvanic isolation is not provided. Dangerous voltages are
present when connected to the AC line. It is the responsibility of the
designer to ensure adequate safeguards are in place to protect the end
user from electrical shock.
- Synchronized to an external clock, or
- Synchronized to other HV9901s, where the synchronized
frequency is the highest free-running frequency.
