MM1305BWBE简介:2000/盘
电池剩余功率检测芯片
Remaining Battery Power Display
---------------------------------

Outline
This IC detects battery voltage and displays the power remaining in the battery. Portable equipment is
becoming more and more popular, and one standard function of this type of equipment is remaining battery
power display. This IC has four threshold voltages built in. Since their respective detection circuits share the
reference voltage on one chip, the detection voltage for each lags in the same direction. Thus, there is much
smaller error as compared to the reciprocal error resulting from combining single circuits.
Also, the stepped display of remaining battery power as in nickel cadmium, nickel hydrogen and lithium ion
batteries is enabled through super high precision voltage detection of ±1%.
Features
1. A separate line-up of detection voltages for alkaline magnesium and nickel cadmium and nickel hydrogen
batteries.
Alkaline magnesium : 1.350V /1.285V /1.200V /1.100V
Nickel cadmium, nickel hydrogen : 1.275V /1.245V /1.205V /1.100V
2. Super high precision detection voltage : ±1% typ.
3. Low current consumption : Waiting : 1.5µA
Detection : 12µA
4. Ripple absorption pin
Enables continuous ripple absorption and suppresses detection errors.
5. Built-in hysteresis voltage
Package
VSOP-8A (MM1305XW, MM1305AW, MM1305BW)
