MC3425 Datasheet | Motorola Semiconductor

Order this document by MC3425/D MC3425 Power Supply Supervisory/ Over and Undervoltage Protection Circuit The MC3425 is a power supply supervisory circuit containing all the necessary functions required to monitor over and undervoltage fault conditions. These integrated circuits contain dedicated over and undervoltage sensing channels with independently programmable time delays. The overvoltage channel has a high current Drive Output for use in conjunction with an external SCR Crowbar for shutdown. The undervoltage channel input parator has hysteresis which is externally programmable, and an open- collector output for fault indication. - Dedicated Over and Undervoltage Sensing POWER SUPPLY SUPERVISORY/ OVER AND UNDERVOLTAGE PROTECTION CIRCUIT SEMICONDUCTOR TECHNICAL DATA - - - - - - Programmable Hysteresis of Undervoltage parator Internal 2.5 V Reference 300 m A Overvoltage Drive Output 30 m A Undervoltage Indicator Output Programmable Time Delays 4.5 V to 40 V Operation 8 1 P1...
