5 V supervisor with battery switchover

Features

■ 5 V operating voltage

■ NVRAM supervisor for external LPSRAM

■ Chip-enable gating (STM818 only) for external

LPSRAM (7 ns max prop delay)

■ RST and RST outputs

■ 200 ms (typ) t

rec

■ Watchdog timer - 1.6 sec (typ)

SO8 (M)

■ Automatic battery switchover

■ Low battery supply current - 0.4 µA (typ)

■ Power-fail comparator (PFI/PFO)

■ Low supply current - 40 µA (typ)

■ Guaranteed RST (RST) assertion down to

= 1.0 V

■ Operating temperature:

TSSOP8 3 x 3 (DS)⁽¹⁾

–40 °C to +85 °C (industrial grade)

■ RoHS compliance

– Lead-free components are compliant with

the RoHS directive
