DESCRIPTION

The L9704 is a bipolar monolithic integrated circuit for monitoring the statusof up to eight contacts connected to the power supply (battery).

It contains eight contact sense inputs and eight microcomputer compatible three-state outputs.

■ OPERATING DC SUPPLY VOLTAGE RANGE 5V TO 25V

■ SUPPLY OVERVOLTAGE PULSE UP TO 40V

■ VERY LOW STANDBY QUIESCENT CURRENT 0.2mA

■ INTERNAL CLAMPING DIODES AT CONTACT INPUTS TO VS AND GND

■ INPUT PULSE CURRENT CAPABILITY UP TO + 50mA, – 75mA

■ NOMINAL CONTACT CURRENTS OF 10mA

DEFINED BY EXTERNAL CONTACT SERIES

RESISTORS RIN1-8

■ CONTACT STATUS MONITORING BY COM

PARING THE RESISTANCE AT CONTACT

SENSEINPUTS WITH THEINTERNAL REFERENCE RESISTOR VALUE

■ HIGH IMMUNITY DUE TO RESISTANCE COMPARISON WITH HYSTERESIS
