8T308B98SA-LC module is a type of current-drive signal control circuit, specifically developed for small capacity motors and low-power fans commonly found in home appliance and office equipment, such as refrigerators, air-conditioners, microwave ovens and printers. The 8T308B98SA-LC module offers high reliability, low power consumption and high integration and can drive current loads of up to 1A, with the over-current protection feature protecting the motor driving circuit and the load from excessive current when the temperature rises. This article will introduce the application field of 8T308B98SA-LC module and its working principle.

Applications of 8T308B98SA-LC Modules: As mentioned above, 8T308B98SA-LC module is ideal for many motor-driven household and office equipment. For example, electric refrigerators, air conditioners, microwave ovens, and other home appliances can use 8T308B98SA-LC modules to drive small cooling and heating fan motors. In a microwave oven, the 8T308B98SA-LC module is responsible for driving the rotary motor that controls the magnetron for heating and cooking food. In air conditioners, the 8T308B98SA-LC module switches the frequency of the fan motors allowing the user to adjust the temperature.

Besides home and office equipment, 8T308B98SA-LC modules can also be used in vending machines and other embedded mechanical equipment, such as industrial robots or automatic doors. As mentioned above, the 8T308B98SA-LC module features a high-reliability, low power consumption, and high integration which makes it ideal for use in these kinds of devices.

Working Principle of 8T308B98SA-LC Module: The steering circuit of 8T308B98SA-LC module consists of a P-type MOSFET and an N-type MOSFET. The P-type MOSFET is used to drive the fan motors or small load equipment, while the N-type MOSFET is used to protect the circuit from over-current. When the current is too high, the N-type MOSFET will conduct the current overload more easily and protect the circuit and load.

In addition, the 8T308B98SA-LC module has a built-in current-limiting resistor which prevents excessive current from flowing to the fan motor or load. It also has a built-in temperature sensor which can detect the temperature of the motor driving circuit and the load and trigger the protection circuit when the temperature reaches a certain level.

The 8T308B98SA-LC module is a high-efficiency and reliable signal control circuit. It is ideal for many home and office appliances, industrial robots, automatic doors, and vending machines. With its current-limit and temperature sensing capabilities, it can ensure a stable and reliable operation of connected components. It is also relatively inexpensive and can be easily integrated into a variety of applications.
