Features & Applications
Exar’s state of the art solutions provide high efficiency, low quiescent current, small size and the industry’s best price/performance ratio.
Many of Exar’s most advanced power management ICs are offered in thermally enhanced, lead-free DFN or QFN packages for the best blend of low thermal impedance and minimal circuit board area.
Exar power management products can be used as stand alone solutions but are designed to be used together to create a complete power management system. This product group includes low drop out linear regulators (LDOs), DC to DC switching regulators, PWM controllers, charge pumps, and microprocessor supervisors.
The SP690A/692A/802L/802M/805L/805M are a family of microprocessor (µP) supervisory circuits that integrate a myriad of components involved in discrete solutions to monitor power supply and battery-control functions in µP and digital systems. The series will significantly improve system reliability and operational efficiency when compared to discrete solutions.
The features of the SP690A include a watchdog timer, a µP reset and backup-battery switchover, and power-failure warning, a complete µP monitoring and watchdog solution. The series is ideal for applications in automotive systems, computers, controllers, and intelligent instruments. All designs where it is critical to monitor the power supply to the µP and it’s related digital components will find the series to be an ideal solution.
