Powtech PT6105
The PT6105 is a highly integrated, digitally programmable, charging/discharging management IC for 3 to 7 serially connected Li-Ion or LiFePO4, batteries used in portable electrical tools or other multi-cell battery powered systems. It contains a multi-channel 10-bit ADC digitizing battery voltages, environment temperature, and battery discharge current. The converted data is transferred to MCU via I2C interface and is used for battery balancing and safety protections against battery over-voltage, under-voltage, discharging over current, and over temperature.| Part No. | PT6105 |

GENERAL DESCRIPTION
The integrated battery balance circuitry could deliver a programmable shunt current as high as 200mA without the need of external transistors. The PT6105 buffers both DC and PWM (Pulse Width Modulation) MOSFET control signals generated from MCU to drive an electrical motor. Key parameters in the PT6105 are programmable by a microprocessor through an I2C interfacing port, which features customers to achieve flexible and optimal multi-cell Li-ion/LiFePO4 battery charging/discharging progress control and safety protection. The package is QFN-24. PIN ASSIGNMENT VIN 24 23 22 21 20 19 1 18 CH_FET VB7 2 17 DS_FET VB6 3 VB5 4 PT6105 QFN24 16 DS_CS 15 DS_REF VB4 5 14 SDA VB3 6 13 SCL 7 8 9 10 11 12FEATURES
