MAXIM INTEGRATED PRODUCTS  MAX793TESE+  芯片, 微处理器监控器, 5.5V, NSOIC-16

The is a 3V/3.3V microprocessor supervisory circuit in 16 pin NSOIC package. The microprocessor µP supervisory circuit will monitor and control the activities of +3V/+3.3V µPs by providing backup-battery switchover. The backup-battery voltage can exceed VCC and permit the use of 3.6V lithium batteries in systems using 3V to 3.3V for VCC. This device is used in embedded controllers, intelligent controllers, battery powered computers.
