Quad PWM Relay Driver  
FEATURES  
DESCRIPTION  
Maintains Constant Average  
Relay Voltage With Varying  
Supply Voltages  
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 application's sec-  
tion concerning the relay selection.) VBUS must be higher then the rated  
relay voltage. Short circuit protection is provided on chip with periodic retry.  
VBUS Voltages up to 42.5V  
Up to 50mA per Relay  
Integrated Schottky Flyback Diodes  
Individual Relay Control Inputs  
Short Circuit Protection  
The UC3702 requires a +5V logic supply as a reference. Two external re-  
sistors program the effective relay voltage and a capacitor sets the nominal  
operating frequency. Internal Schottky diodes eliminate the need for any  
external power components.  
In typical applications, the UC3702 grants the user the flexibility to choose  
the most cost effective relay without the added burden of generating a sep-  
arate relay supply voltage. The UC3702 will even function with a poorly  
regulated supply VBUS, containing significant 100Hz or 120Hz ripple.
