Low-Power, Single/Dual-Level Battery Monitors

with Hysteresis

_______________________________________________________________________________________

Note 1: Production testing done at TA = +25°C, limits over temperature guaranteed by design only.

Note 2: Percentage of selected factory-fixed HTH- or LTH- threshold voltage.

Note 3: Percentage of 1.05 ✕ (selected factory-fixed threshold voltage).

Note 4: Percentage of 615mV voltage reference.

Note 5: Percentage of 585mV voltage reference.

Note 6: Guaranteed by design.

Note 7: VSUPPLY is BATT or VDD.

ELECTRICAL CHARACTERISTICS (continued)

(BATT = 1.0V to 5.5V or VDD = 1.6V to 5.5V, TA = -40°C to +85°C, unless otherwise specified. Typical values are at TA = +25°C.)
