The TC426EPA is a quad dual-output, low-drive-voltage logic gate driver from Microchip Technology.

In PMIC (Power Management Integrated Circuit) – Gate Drivers category, the TC426EPA resides in the ‘high-driving power’ segment, providing up to a 12-mA sink current on each output. It features CMOS-compatible inputs, active-high and active-low outputs, and has control pins for output enable and power-down with high immunity to noise.

The TC426EPA is ideal for driving various applications including fan, motor and LED control, as well as in many consumer products including document scanners, dishwashers and washing machines, design engineers can get the best use out of the product. In addition, its low operating voltage (1.8V to 7.0V) ensures it is a suitable fit for a variety of advanced consumer products.

The TC426EPA also offers a wide range of protection features, such as undershoot, overshoot, short circuit protection and output stage latching. It also integrated thermal shutdown to protect the device from overheating and latch-up immunity. All these features enable the device to exceed safety standards up to the SELV and PELV levels.

The TC426EPA circuit module features an enable pin for the output state control and an external pull-up capacitor for suiting various application requirements. The enable input is an active-low logic state. When it is low, the outputs are low; when it is high, the outputs are high. The external pull-up capacitor can be adjusted to match the application requirements.

The TC426EPA also incorporates an over-current protection circuit, which limits the current flowing through the outputs when the device is in saturation mode. Moreover, the device also features a latch-up protection circuit, which ensures that the device returns to its constant maximum current when it locks in the case of excessive current.

The TC426EPA is suitable for a wide variety of PMIC applications, such as driving loads in power distribution systems, power supplies, motor drives, LED lighting and control systems. In these applications, its high-drive current and low-drive-voltage make it well-suited for providing reliable switching performance.

In conclusion, the TC426EPA is a quad dual-output logic gate driver designed for PMIC applications. It offers a wide range of features such as CMOS-compatible inputs, active high and active low output stages, wide voltage-range operation, over-current protection, and latch-up protection. Thus, providing the engineer with a reliable solution for driving various applications.
