6~7 battery protection IC

Application Areas

CW1073

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.

• Working state 15ÿA (25°C) • Sleep state

5ÿA (25°C) ÿPackage : SSOP24

The CW1073 series is a lithium battery protection chip with built-in high-

precision detection circuit and delay circuit, suitable for 6-7 series lithium-ion

batteries or lithium polymer battery packs. It provides overcharge detection, over-

discharge detection, over-current detection, balancing, disconnection detection,

and high and low temperature protection for lithium battery packs.
