LA-POWR1014/A Automotive Family


A General-Purpose Power-Supply Monitor and Sequence Controller

LA-POWR1014

The LA-ispPAC-POWR1014 device replaces power management functions typically requiring multiple ICs, including Reset Generators, Voltage Supervisors, Sequencers and Trackers. In addition, the LA-ispPAC-POWR1014A device replaces Analog-to-Digital Converter (ADC) ICs used for power supply voltage measurements, controlled through a standard I2C interface.

Automotive electronics are becoming more sophisticated, and there is a need for the use of multiple complex ASIC, ASSP and FPGA devices on these boards. These devices complicate the power management algorithm and the current simple single-function Power management ICs are no longer able to provide a reliable solution. The Power Manager II device is not only able to meet the power management needs of these complex boards, but also increase system reliability by monitoring supply faults with high accuracy.

All Power Manager devices provide a standard, off-the-shelf programmable mixed signal solution for power management that enhances reliability and speeds time-to-market. Analog features such as input comparator thresholds and digital functions such as supply control sequences are programmed into non-volatile E2CMOS® elements on the devices using an IEEE1149.1 protocol.
