TPAU3G S1G

Diodes - Rectifiers - Single

A TPAU3G S1G is a single chip ultra-low power, low supply voltage gate drive optocoupler that features a number of advanced features. Specifically designed for SO-8 and D-Pak packages, the TPAU3G S1G offers a compact size and operability from 4.5V to 18V at a maximum frequency of 1 MHz.

The TPAU3G S1G is designed for use as a general-purpose application field such as interface dimming, motor control, and driving logic blocks. It is also used as an optocoupler for high-frequency, high-voltage applications. The device allows the driver to be isolated from the logic, eliminating the need for complex gate drive circuitry.

The basic working principle behind the TPAU3G S1G lies in its construction. It consists of two integrated circuit (IC) components in a single IC. The first IC contains the photodiode and emitter, while the second contains the MOSFET and associated circuitry. Photons produced by the emitter are detected by the photodiode and converted into electrical signals. These electrical signals pass through a circuit composed of various diodes, and are then applied to the MOSFET gate.

The voltage applied to the MOSFET gate is what controls the internal current flow. When the voltage applied is low, the MOSFET will remain OFF, preventing current from flowing. However, when the voltage applied is high, the MOSFET will switch ON, allowing current to flow. This is how the TPAU3G S1G selectively controls current flow.

The TPAU3G S1G also features a low-power standby mode that is activated when the voltage applied to the photodiode drops below a certain threshold. This is an effective way to significantly reduce the device’s power consumption, especially during periods of low usage. In addition, through its advanced design, the TPAU3G S1G can easily be used in various applications without the need of any additional circuitry.

Overall, the TPAU3G S1G is an extremely reliable and efficient single-chip gate drive optocoupler that offers a number of advanced benefits. Due to its ultra-low power mode, wide operating voltage range and simple to use circuitry, the device is ideal for a variety of applications.
