The LA-ispPAC-POWR1014/A device provides 10 indepen- dent analog input channels to monitor up to 10 power supply test points. Each of these input channels has two independently programmable comparators to sup- port both high/low and in-bounds/out-of-bounds (win- dow-compare) monitor functions. Four general-purpose digital inputs are also provided for miscellaneous con- trol functions. The LA-ispPAC-POWR1014/A provides 14 open-drain digital outputs that can be used for controlling DC-DC converters, low-drop-out regulators (LDOs) and opto- couplers, as well as for supervisory and general-pur- pose logic interface functions. Two of these outputs (HVOUT1-HVOUT2) may be configured as high-voltage POL#1 POL#N CPU LA-ispPAC-POWR1014A Signals 4 Timers ADC* *LA-ispPAC-POWR1014A only. 4 Digital Inputs I2C Interface I2C Bus* Primary Supply Primary Supply Primary Supply Primary Supply Primary Supply 12 Digital Outputs Other Control/Supervisory CPLD 24 Macrocells 53 Inputs 2 MOSFET Drivers 3.3V 2.5V 1.8V LA-ispPAC-POWR1014/A Automotive Family In-System Programmable Power Supply Supervisor, Reset Generator and Sequencing Controller |
