CW1073 has built-in MOSFET driving function and supports external
PWM signal to control DO_PWM terminal output through DCTRL terminal to
realize motor speed regulation and soft start function.
The CW1073 series is a lithium battery protection chip with built-in highprecision
detection circuit and delay circuit, suitable for 6-7 series lithium-ion
batteries or lithium polymer battery packs. It provides overcharge detection, overdischarge
detection, over-current detection, balancing, disconnection detection,
and high and low temperature protection for lithium battery packs.
