Part Name(s) : UC1702 UC2702 UC3702 UC2702D UC2702DTR UC3702D UC3702N TI
Texas Instruments
Description : Quad PWM RELAY Driver View

DESCRIPTION
The UC3702 Quad RELAY Driver is intended to drive up to four RELAYs from logic inputs using an unregulated RELAY voltage supply. The RELAYs are driven from the Bus supply in a power efficient PWM converter fashion. The RELAY coil is used as the inductive element. (See the applications section concerning the RELAY selection.) VBUS must be higher then the rated RELAY voltage. Short circuit protection is provided on chip with periodic retry.

FEATURES
• Maintains Constant Average RELAY Voltage With Varying Supply Voltages
• VBUS Voltages up to 42.5V
• Up to 50mA per RELAY
• Integrated Schottky Flyback Diodes
• Individual RELAY Control Inputs
• Short Circuit Protection
• User Selectable Operating Center Frequency and RELAY Voltage
• Global Reset

Part Name(s) : HV9901DB1 SUTEX
Supertex Inc
Description : Universal RELAY Driver View

Introduction
The HV9901 is a universal RELAY driver employing PWM switching techniques utilizing the RELAY coils inductance to provide efficient operation over a wide supply voltage range. RELAY drive is constant-current.  Pull-in current, pull-in time, and hold current are all programmable via 2 resistors and a capacitor.  An adjustable regulator provides 1mA for external circuitry.

The HV9901DB1 demo board contains all the circuitry necessary to demonstrate the operation of the HV9901. Included on-board are a full-wave input rectifier, fuse, the HV9901, and a 10A RELAY.  Provisions for connecting an external RELAY are available.  The circuit may be modified to accomodate the drive requirements of other RELAYs.
