The document provides information about the ispPAC-POWR1014/A In-System Programmable Power Supply Supervisor, Reset Generator and Sequencing Controller from Lattice Semiconductor Corp. The product simultaneously monitors up to 10 power supplies, provides up to 14 output control signals, and has programmable digital and analog circuitry. It includes an embedded PLD for sequence control and four independent programmable timers. Additionally, it features 10 independent analog monitor inputs with two programmable threshold comparators per input, hardware window comparison, and a 10-bit ADC for I2C monitoring (ispPAC-POWR1014A only). The product also includes high-voltage FET drivers for power supply ramp up/down control and programmable current and voltage output. It has a 2-wire (I2C/SMBus compatible) interface for comparator status monitor, ADC readout, direct control of inputs and outputs, and power sequence control.
The ispPAC-POWR1014/A is a general‑purpose power‑supply monitor and sequencing controller that integrates a 24‑macrocell CPLD, four programmable timers, and a 10‑bit ADC. It supports up to ten independent analog inputs, fourteen open‑drain digital outputs, and high‑voltage FET driver capability for controlling DC‑DC converters and LDOs.
The device operates from a 2.8 V to 3.96 V core supply, works over an industrial temperature range of –40 °C to +85 °C, and is supplied in a 48‑pin TQFP package. The datasheet includes pin descriptions, absolute maximum ratings, recommended operating conditions, and detailed specifications for analog, digital, and timing functions.
