Cellwise CW1073
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. 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.| Part No. | CW1073 |
