ISPPAC-POWR1014-02T48I

Power Supply Controllers, Monitors Overview

The ISPPAC-POWR1014-02T48I is an in-system programmable power supply supervisor, reset generator, and sequencing controller from the Power Manager II family. It integrates analog and digital functions for managing up to ten power supplies simultaneously. The device features a 24-macrocell CPLD for implementing state machines and combinatorial logic, four independent programmable timers with intervals ranging from 32 µs to 2 seconds, and ten independent analog monitor inputs. Each input includes two programmable threshold comparators and hardware window comparison capabilities. It provides fourteen output control signals, including high-voltage FET drivers for ramp-up/down control. Configuration is stored in non-volatile E²CMOS memory, allowing reprogramming via USB.
