Data Sheet
8-Channels Switch for Multi-Cells Li+/Polymer Battery Pack AP9106
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 directly 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.
