Product introduction

This module is suitable for a single -section 3.7V lithium battery. The function is to prevent the battery from excessive discharge and cause permanent damage to the battery. The module will turn off the output function when the battery voltage is lower than 2.8V.In addition to the output, this module also has electronic switching functions. For example, when our device needs to work in large current, the mechanical switch is generally large and expensive because of the large current.Small switches to control the throughout of large currents. Note that because the voltage of the lack of voltage protection function of this module is turned off when the battery voltage is lower than 2.8V, the electronic switch function is also invalid when the battery voltage is lower than 2.8V.

Input voltage: 0-5V (Typical 3.7V lithium battery under voltage off voltage: 2.8V

Restore the turnover voltage: 3V

MOS tube parameters: resistance 20V/maximum current 100A/internal resistance 3.3 millimeter/complete turnover voltage 2V over current capacity: continuous 10A slightly heating, short time 30A, maximum instant 100A (theoretical)

Note: When this kind of module is emotionally load on the market, it is easy to damage. For example, the reverse high voltage of the brush motor will break through MOS and cause damage.
