The TPS2811P is a low-voltage, low-current, high-side switch designed to drive inductive and other load switches. It is part of Texas Instruments’ wide range of Power Management Integrated Circuit (PMIC) products. Generally classified as a Gate Driver, the TPS2811P offers excellent switching characteristics, allowing transmission of both analog and digital signals.

Application Fields:

This PMIC is applicable in a wide range of applications where precise timing and low on-resistance switching of single and multiple loads is needed. These include:

• Power inverters and motor drives
• Automotive voltage level shifting sensor applications
• High side switching drivers for audio, video and computer systems
• Load switches for power supplies and battery charge management applications

Working Principle:

The TPS2811P operating principle is essentially a P-channel MOSFET in a high-side configuration. By applying a low voltage to the Gate for both ON and OFF states, the circuit can provide precise switching with low Rdson on-resistance. This makes the TPS2811P ideal for today’s low voltage, low power demands.

The circuit’s low Rds(on) allows it to drive heavy loads while ensuring low power dissipation. The internal circuitry of the TPS2811P is designed using advanced technologies to minimize power losses in switching states both ON and OFF.

The TPS2811P is designed to minimize EMI issues with careful edge-rate transitions to ensure optimal switching performance in noisy environments. The circuit’s wide operating temperature range of -40°C to 125°C make it suitable for applications in extreme environments.

The TPS2811P is packaged in the 8-pin smallest size TSSOP package available and is available in both the TPS2811PPG and TPS2810PPG versions to suit different application requirements.
