HV9901
Universal Relay Driver
Features
General Description
•
•
•
•
•
•
The HV9901 universal relay driver provides high-efficiency driving for low-voltage relays with supply voltages 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
Programmable Pull-in Current, Pull-in Time and
Hold Current
Applications
•
•
•
•
Industrial Controls
Relay Timers
Solenoid Drivers
Home Automation
The IC includes two high-voltage linear regulators. The
first one is for providing power to internal control circuitry. The second one has an adjustable output voltage and a 1 mA output current capability to support
external circuitry, such as a microcontroller control circuit.
The pull-in current, pull-in time and hold current for the
relay are individually programmable through two resistors and a capacitor. PWM switching can be synchronized with an external clock or with another HV9901
operating at a higher frequency.
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 suppressed by operating at a PWM frequency exceeding
20 kHz.

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.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
