Pin Function Specifications (6-Pin WSON Package)
The TPD2E001DRLR is a 6-pin device, primarily designed for ESD protection. Here is the comprehensive pinout description:
Pin Number Pin Name Function Description 1 I/O Line 1 (Pin 1) Signal Line 1 (Protected Line 1) - This is the first signal line to be protected. When voltage exceeds the rated threshold, this pin will clamp the excess voltage to a safe level. 2 I/O Line 2 (Pin 2) Signal Line 2 (Protected Line 2) - Similar to Pin 1, this pin is also part of the protection circuit. Any overvoltage on this line will be suppressed to prevent damage. 3 VSS (Pin 3) Ground Pin (VSS) - This is the ground reference for the device. It is used to complete the circuit and should be connected to the system ground. 4 VSS (Pin 4) Ground Pin (VSS) - Another ground pin. Ensures stability and low-resistance connection to the ground, necessary for proper ESD clamping operation. 5 I/O Line 3 (Pin 5) Signal Line 3 (Protected Line 3) - This pin provides protection for another signal line, effectively clamping any transient voltages on this line. 6 I/O Line 4 (Pin 6) Signal Line 4 (Protected Line 4) - The final protected signal line in the device, providing transient voltage suppression to prevent system damage.Circuit Principle
The TPD2E001DRLR functions as a TVS diode for ESD protection. The core operation is as follows:
The device monitors voltage levels on the I/O Lines. When an overvoltage or transient event (like an ESD spike) occurs, the TVS diodes (embedded in the chip) clamp the voltage to a safe level. The VSS pins are connected to the system ground, forming the reference for the voltage clamping mechanism. The device is used in environments where sensitive electronics (e.g., logic circuits, high-speed data interface s) are at risk of ESD damage.FAQ - Frequently Asked Questions
