P-channel MOS transistor SI2301 can be Used for LED and Motor Driving Applications
MOS transistor is transformed into output current by the change of input voltage, and the power consumption of MOS transistor in the on state is very low, which can realize efficient power utilization. This paper introduces a commonly used MOS product SI2301, which can be used in LED, motor drive and inverter applications.
Hottech, a P-channel MOS transistor, has good electrical characteristics. It can withstand a maximum drain-source voltage of 20V, a gate voltage of 8V, a continuous drain current of 2.3A, a drain-source on-resistance of 0.112Ohm, a minimum gate threshold voltage of 0.4V, a maximum gate threshold voltage of 1V and a dissipation power of 0.4W.. SI2301 has the characteristics of low on-resistance and low gate driving voltage, and is suitable for low-power DC-DC converters. The weight of the whole machine is about 0.008 g, which is suitable for portable applications. The switch has good performance and is suitable for being a load switch in the circuit.
SI2301 adopts SOT-23 package, which is easy to solder, compact in size and very lightweight, and is suitable for applications requiring compact design, such as portable devices and small Internet of Things devices. The product has very good reliability and stability, mature technology, normal operation in a wide temperature range and good electrical performance.
The characteristics of this product make it widely used in power management, LED, motor drive, inverter, wearable, smart small household appliances, mobile phones, tablets, automotive electronics and other fields.
Take the application of SI2301 as an example, it is used as a current regulator and switch in the LED lighting control circuit, and it controls the brightness and color temperature of LED lamps. When the gate voltage in the circuit is higher than 0.4V, the SI2301 tube is turned on, and the brightness of LED lamp is controlled by inputting different gate voltages.
In addition, for example, SI2301 is also promising in miniaturization application scenarios such as smart and convenient small fans and smart electric toys. In motor driving, when the gate voltage of SI2301 is higher than 0.4V, the tube is turned on, and the motor speed can be controlled by inputting different voltage values.
In low-power power inverter, SI2301 is also used to realize DC-AC inverter of power supply, which is used in uninterruptible power supply and emergency power supply system. By adjusting the gate voltage of SI2301, when the gate voltage is higher than 0.4V, it will be turned on, and the inverter control of power supply will be realized. In this application, attention should be paid not to exceed the maximum voltage range of MOS.
In addition, SI2301 can also play its fast switching role. In the one-key switching circuit, one-key switching can be realized through the change of gate threshold voltage. This circuit can also be used in smart door locks, monitors, smart emergency lights, smart speakers and other scenes.
