Controller IC Chip – MAX1773AEUP MAX1773A chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0670)
The MAX1773/MAX1773A highly integrated ICs serveas the control logic for a system with multiple powersources. They directly drive external P-channelMOSFETs to select from an AC adapter and dual bat-tery sources for charge and discharge. The selection ismade based on the presence of the power sources andthe state of the batteries. The MAX1773/MAX1773Adetect low battery conditions using integrated analogcomparators and check for the presence of a batteryby using battery thermistor outputs. The MAX1773/MAX1773A are designed for use with abuck topology charger. They provide a simple and easilycontrolled solution to a difficult analog power control prob-lem. The MAX1773/MAX1773A provide most of the powersource monitoring and selection, freeing the system powermanagement microprocessor (mR) for other tasks. This notonly simplifies development of the power managementfirmware for the mR but also allows the mR to enter standby,thereby reducing system power consumption.The MAX1773A is recommended for new designs.
