TPS3619-33, BACKUP-BATTERY SUPERVISORS

The TPS3619 and TPS3620 families of supervisory circuits monitor and control processor activity by providing backup-battery switchover for data retention of CMOS RAM.

During power on, RESET is asserted when the supply voltage (VDD or VBAT) becomes higher than 1.1 V.

Thereafter, the supply voltage su
