Maxim Integrated Products Intros MAX1773 IC

December 03, 2000 by Jeff Shepard

Maxim Integrated Products (Sunnyvale, CA) recently introduced the MAX1773 IC that serves as the control logic for a system with multiple power sources. The device directly drives external P-channel MOSFETs to select from an ac adapter and dual battery sources for charge and discharge. The selection is based on the presence of the power sources and the state of the batteries.

The MAX1773 is designed for use with a buck-topology charger. It was designed to provide a simple and easily-controlled solution to difficult analog power control problems. The MAX1773 provides most of the power source monitoring and selection, freeing the power management microprocessor for other tasks. This allows the microprocessor to enter standby, thereby reducing system power consumption.

The MAX1773 is available in a 20-pin TSSOP package. It is specified for the extended-industrial temperature range, -40 degrees C to 85 degrees C. Prices start at $2.82 for quantities of 1,000 and up.
