  • CMS6021B

    CMS6021B has an internal integrated 2-channel linear voltage regulator, which can be used in the field of power tools with triggers such as lithium electric wrenches and lithium electric drills.

    Datasheet >

    CMS6021B has two fixed outputs, a 12V power supply circuit with a load capacity of 60mA that powers an internal 5V power supply and an external gate driver. A 5V power supply circuit with a load capacity of 30mA can power the MCU and its peripherals.

    CMS6021B has a power-on self-test function, integrated VBAT under-voltage protection, over-temperature protection, current limit detection, enable shutdown, and voltage divider output and other functions.

    Features

    >   Enable shutdown or undervoltage to achieve zero standby current

    >   5V regulated output with 30mA load capacity and current limit protection

    >   12V regulated output with 60mA load capacity and current limit protection

    >   Built-in power-on self-test function, can be used optionally

    >   Built-in enable shutdown delay function, built-in delay time of 16ms

    >   Built-in power supply undervoltage detection function, undervoltage threshold of 5.3V/4.6V, and built-in 16ms filtering for undervoltage protection, so as to prevent the output from turning off due to instantaneous interference.

    >   Built-in button port low voltage protection function, through the external Zener diodes, to achieve the target undervoltage point selection

    >   Built-in over-temperature protection function, over-temperature threshold: 160℃/140℃

    >   Built-in power supply voltage divider output module, voltage divider ratio: 1/11

    >   Electrostatic Discharge Capability: 4000V (HBM)
