LA-ispPAC-POWR1014/A is a programmable power supply supervisor, reset generator and sequencing controller from the automotive family of Lattice Semiconductor Corp. Features include simultaneous monitoring of up to 10 power supplies, provision of up to 14 output control signals, programmable digital and analog circuitry, AEC-Q100 tested and qualified, embedded PLD for sequence control, embedded programmable timers, analog input monitoring, high-voltage FET drivers, and 2-wire (I2C/SMBus™ compatible) interface.
The LA-ispPAC-POWR1014/A combines programmable logic and analog monitoring to supervise up to ten power supplies and generate reset and sequencing signals. It features a 24‑macrocell CPLD, four independent timers, a 10‑bit ADC, and high‑voltage FET drivers that can output up to 8 V for gate control.
The device operates from a 2.8 V to 3.96 V core supply, supports I²C/SMBus communication, and is qualified for automotive temperature ranges from –40 °C to +105 °C. Pin‑out includes 10 analog monitor inputs, 4 digital inputs, and 14 open‑drain digital outputs, all configurable via JTAG or the on‑chip CPLD.
