It is well suited for applications with power levels up to 10A, and supports adjustable current limit settings, adjustable Slew-Rate control and adjustable reference voltage. It is also suitable for industrial applications, as it can provide up to 15W of power with 100ns response time. The device is also 3.3V and 5V compatible.

Working principle of TPS25910RSAT

The TPS25910RSAT is designed to protect electronic systems against over-voltage and over-temperature events. It is controlled by an adjustable voltage-mode control loop, which senses the power converter’s output voltage and modifies the gate drive signal to the power transistor. The output voltage of the power converter is monitored by the programmable current limit and SoftStart™ settings. The TPS25910RSAT outputs a low-side gate drive signal and is also capable of being driven by a complementary PWM signal for higher performance applications.

The TPS25910RSAT’s over-voltage protection (OVP) circuit monitors the output of the power converter and shuts down the device when the output voltage exceeds the user-set threshold. The over-temperature protection (OTP) circuit monitors the temperature of the device and shuts it down when it exceeds the user-set threshold. Additionally, the device is equipped with a thermal shutdown (TSD) circuit, which will shut down the device when the internal temperature exceeds the user-set threshold.
