SP691A_05 Datasheet, PDF (3/24 Pages) Sipex Corporation – Low Power Microprocessor Supervisory with Battery Switch-Over

ELECTRICAL CHARACTERISTICS
V_CC = +4.75V to +5.5V for the SP691A/800L, V_CC = +4.5V to +5.5V for the SP693A/800M, V_BATT = +2.8V, and T_AMB = T_MIN to T_MAX unless otherwise
noted. Typical values apply at T_AMB=+25^OC.
