Transistors - FETs, MOSFETs - Arrays

The ALD212900SAL is an integrated four-channel MOSFET Array from LEM Holdings, Inc. It is a four-channel, depletion-mode array that is mainly used for low- to high-speed logic level shifting and motor control applications for motor on/off control.

The device features a very low on-resistance value of 1.2 ohms and a withstand voltage of 28 V, while providing improved ESD protection of ±15 kV. This makes it suitable for applications where switching, level shifting and high current is necessary. The ALD212900SAL is also RoHS-compliant.

In terms of its operating principles, the ALD212900SAL is designed such that it will create an open channel where the gate to source voltage is sufficiently negative, which allows the current to pass through. When the voltage is close to zero, the channel is closed, and the current does not flow. When the voltage between gate and source is sufficiently greater than the threshold voltage, the channel will open, and the current will flow.

The ALD212900SAL is mainly used for applications such as motor control, H-bridge motor control, line-powered motor control, wireless connectivity, smart phone docking stations, and lineart motor control.

Due to its low on-resistance, the ALD212900SAL enables low power consumption and reduced heat dissipation. It also exhibits high immunity to electromagnetic interference (EMI), making it suitable for applications with high EMI requirements.

To ensure its reliable performance, the device features a 5-pin SOT-23 package, which ensures a tight and reliable fit that allows the device to remain secure even in vibration-prone applications or when subjected to large temperature changes.

The ALD212900SAL is available in both single and dual package formats, allowing for maximum flexibility and cost savings in product design. In addition, the device also features an integrated ESD protection of up to ±15 kV.

Overall, the ALD212900SAL is an integrated MOSFET Array with low on-resistance, high withstand voltage and integrated ESD protection of up to 15kV. It is mainly used for motor control, H-Bridge motor control, and line-powered motor control applications.
