Circuit Structure And Application Characteristics

- Jan 23, 2017 -

Electric Bicycle Lithium Iron Phosphate Battery Protection Board Discharge Circuit. The actual application according to different, will use a number of power MOS tube in parallel to reduce the on-resistance to enhance heat dissipation performance.

Normal operation, the control signal to open the MOS tube, the battery terminal of the P + and P- output voltage for the load to use.

However, when the load short-circuit, because the loop resistance is very small, the battery discharge capacity of a strong short-circuit. In this case, the power MOS tube is easily damaged.
