ChipSourceTek-PT6007 is a battery protection chip designed for the protection of 4-7 series lithium-ion/polymer batteries, lithium iron phosphate batteries and lithium titanate batteries. The chip can effectively reduce the risk of battery damage or life shortening caused by overcharge, overdischarge, too mild and too current, and provide a reliable guarantee for the safe use of the battery.

High precision voltage detection circuit

    ChipSourceTek-PT6007 built-in high-precision voltage detection circuit is one of its core functions. It has the following key features:

1. Overcharge detection voltage

•     Radius：VCOV=2.8V to 4.35V; Step 50mV

•     precision：±25mV

    This high-precision detection capability ensures the safety of the battery during the charging process and avoids the potential dangers caused by overcharging.

2. Overcharge lag voltage

•     Radius：VΔCOV=0~300mV; Step 100mV

    This feature improves the stability of the system by setting the lag voltage to prevent frequent triggering of the protection mechanism.

3. Overdischarge detection voltage

•     Radius：VCUV=1.5V to 2.9V; Step 100mV

•     precision：±80mV

    Accurate overdischarge detection can prevent the battery from overdischarge, thus extending the battery life.

4. Over-discharge lag voltage

•     Radius：VΔCUV=200mV~900mV; Step 100mV

    Similar to the overcharge lag voltage, the setting of the overdischarge lag voltage also helps to reduce the false triggering of the system.

Three-stage discharge overcurrent detection circuit

    ChipSourceTek-PT6007 also integrates a three-stage discharge overcurrent detection circuit, as follows:

1. Overcurrent 1 Check the voltage

•     Radius：VPDOC1=50mV to 150mV; Step by 25mV

•     precision：±10mV

2. Overcurrent 2 Check the voltage

•     Radius：VPDOC2= 2 * VPDOC1

•     precision：±20mV

3. Load short circuit detection voltage

•     VPSC=0.5V

•     precision：±50mV

    These three current detection circuits can provide precise protection under different current conditions to avoid battery damage due to overcurrent.

Temperature protection function

    The ChipSourceTek-PT6007 not only detects voltage and current, but also independently sets charge overtemperature protection and discharge overtemperature protection thresholds via external resistors. In addition, it also has a charging low temperature protection function to ensure that the battery can be fully protected in different temperature environments.

Flexible pin configuration

    ChipSourceTek-PT6007 is designed with special CCTL and DCTL pins to directly drive external N-type charging MOSFETs and N-type discharge MOSFETs. Customers can flexibly control charge and discharge MOSFETs according to actual application requirements, and achieve more accurate battery management.

Multi-chip cascade and low power design

    矽源特ChipSourceTek-PT6007支持多芯片级联应用，适用于更多电池串联的场景。其低功耗设计让电池包在存储阶段只消耗微不足道的电流，典型工作状态时为30μA，休眠状态下则小于1μA。这种设计极大地延长了电池的使用寿命，特别是在长期储存时表现尤为突出。

应用实例

    ChipSourceTek-PT6007 is widely used in a variety of devices requiring high reliability battery management, such as electric bicycles, electric scooters, power tools, home appliances, and backup battery systems. Its superior performance and flexibility make it the solution of choice for many industries. For example, in electric bicycles, ChipSourceTek-PT6007 can protect the battery from overcharging and overdischarging, ensuring the safety and endurance of the ride.
