Description: Quad PWM Relay Driver

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 Opera

Applications

* the UC3702 grants the user the flexibility to choose the most cost effective relay without the added burden of generating a separate relay supply voltage. The UC3702 will even function with a poorly regulated supply VBUS, containing significant 100Hz or 120Hz ripple. BLOCK DIAGRAM UDG-96009-1 SL
