ISPPAC-POWR1014A-01TN48I

The Lattice Semiconductor Power Manager II ispPAC-POWR1014A is a versatile power-supply monitor and sequence controller. It integrates programmable digital and analog circuitry, including a 24-macrocell CPLD for sequence control and four independent timers for timing sequences. The device offers 10 independent analog monitor inputs, each with two programmable threshold comparators, and supports hardware window comparison. It also provides up to 14 open-drain digital outputs for controlling DC-DC converters, LDOs, and other power management functions.

This IC operates within a wide supply range of 2.8 V to 3.96 V, with a nominal 3.3 V operation. It is designed for industrial temperature ranges from -40°C to +85°C. The ispPAC-POWR1014A is housed in a 48-pin TQFP package, suitable for surface mount applications. The device also features a 2-wire (I2C/SMBus compatible) interface for monitoring and control, and for the ispPAC-POWR1014A variant, a 10-bit ADC for I2C monitoring.

Key features include simultaneous monitoring of up to 10 power supplies, programmable digital and analog circuitry, and high-voltage FET drivers for power supply ramp-up/down control. The embedded PLD allows for flexible state machine implementation, while the programmable timers enable precise timing for power sequences. The JTAG interface supports in-system programming and access to I2C registers.
