Linear Technology LTC2928CG#PBF

Description
The LTC2928 is a four-channel, cascadable power supply sequencer and high-accuracy supervisor. It allows for easy configuration of power management without software, controlling up to four supplies per device. The LTC2928 supports staged supply sequencing with adjustable time positions and provides fault event reporting with diagnostics. It features a selectable system shutdown on fault and 1.5% undervoltage monitor accuracy. Additionally, it offers overvoltage and/or fault indication, configurable undervoltage and overvoltage thresholds, and charge-pumped enable pins that drive N-channel MOSFETs. The LTC2928 operates from 2.9V to 16.5V and comes in 5mm x 7mm 38-lead QFN and 36-lead SSOP packages.
