The recommended layout for the TPS3707-30DR involves placing the device close to the power source, using short and wide traces for the power lines, and keeping the sense lines away from the power lines to minimize noise. Additionally, a 10nF capacitor should be placed between the VCC and GND pins to filter out noise.
The correct resistor values for the TPS3707-30DR depend on the desired threshold voltage and hysteresis. The datasheet provides a formula to calculate the resistor values based on the desired threshold voltage and hysteresis. Typically, R1 is in the range of 1kΩ to 10kΩ, and R2 is in the range of 10kΩ to 100kΩ.
The maximum voltage that can be applied to the TPS3707-30DR is 18V. Exceeding this voltage can damage the device.
The TPS3707-30DR is rated for operation up to 125°C. However, the device's accuracy and reliability may be affected at high temperatures. It is recommended to derate the device's performance and consider using a heat sink or thermal management techniques in high-temperature applications.
The TPS3707-30DR has a built-in power-up and power-down sequence control. The device will not assert the reset output until the input voltage has reached the threshold voltage. During power-down, the device will de-assert the reset output when the input voltage falls below the threshold voltage minus the hysteresis.
