data sheet 8-channels switch for multi-cells li+/polymer battery pack AP9106 apr. 2012 rev 1. 1 bcd semiconductor manufacturing limited 1 general description AP9106 is 8-channel analog switch which is suitable for up to 6-cells in serial li+/polymer battery pack application. AP9106 has four logic selection inputs (a/b/c/d). when all logic pins are set low, no channel is selected and the chip is turned off with shutdown mode. the a, b, c and d selection pins are compatible with ttl/cmos logic level, can be connected to mcu i/o port di rectly to select the right channel respectively. the vout is output pin to indicate exactly the voltage of each battery cell. aux7, aux8 pins are auxiliary channels, which can be connected to the ntc resistor to transfer the voltage variation into vout pin. AP9106 is available in standard package of tssop-20. features ? 1% matching error between any 2 channels ? up to 6-cells in serial li+/polymer battery e pack application with single chip ? up to 11-cell in serial li+/polymer battery pack e application with dual chip ? ultra low current in shutdown mode: 1.0 a ? compatible with ttl/cmos for logic level ? logic level shift transfer ? small package: tssop-20 applications ? e-bike li+ battery pack ? electric tool battery pack figure 1. package type of AP9106 tssop-20
