Hot-selling and scarce ISPPAC-POWR1014A-01TN48I In-System Programmable Power Supply Supervisor QFP48 spot stock

Product Descriptions

IspPAC-POWR1014/A is a  general-purpose power-supply monitor and sequence  controller, incorporating both in-system programmable  logic and in-system programmable analog functions  implemented in non-volatile E2 CMOS® technology. The  ispPAC-POWR1014/A device provides 10 independent  analog input channels to monitor up to 10 power supply  test points. Each of these input channels has two independently programmable comparators to support both  high/low and in-bounds/out-of-bounds (window-compare) monitor functions. Four general-purpose digital  inputs are also provided for miscellaneous control functions.

The ispPAC-POWR1014/A provides 14 open-drain digital outputs that can be used for controlling DC-DC converters, low-drop-out regulators (LDOs) and optocouplers, as well as for supervisory and general-purpose logic interface functions. Two of these outputs  (HVOUT1-HVOUT2) may be configured as high-voltage MOSFET drivers. In high-voltage mode these outputs can provide up to 12 V for driving the gates of n-channel  MOSFETs so that they can be used as high-side power switches controlling the supplies with a programmable  ramp rate for both ramp up and ramp down. 

The ispPAC-POWR1014/A incorporates a 24-macrocell CPLD that can be used to implement complex state  machine sequencing for the control of multiple power supplies as well as combinatorial logic functions. The status  of all of the comparators on the analog input channels as well as the general purpose digital inputs are used as  inputs by the CPLD array, and all digital outputs may be controlled by the CPLD. Four independently programmable  timers can create delays and time-outs ranging from 32 µs to 2 seconds. The CPLD is programmed using LogiBuilder™, an easy-to-learn language integrated into the PAC-Designer® software. Control sequences are written to  monitor the status of any of the analog input channel comparators or the digital inputs.
