TPS3707-50DGN datasheet by Texas Instruments

TPS3707-50DGN Frequently Asked Questions (FAQs)

• What is the recommended layout for the TPS3707-50DGN to ensure optimal performance?
  The recommended layout for the TPS3707-50DGN 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.
• How do I choose the correct resistor values for the R1 and R2 resistors in the TPS3707-50DGN circuit?
  The values of R1 and R2 depend on the desired threshold voltage and hysteresis. A higher R1 value increases the threshold voltage, while a higher R2 value increases the hysteresis. The datasheet provides a formula to calculate the threshold voltage and hysteresis based on the resistor values.
• What is the maximum voltage that can be applied to the VCC pin of the TPS3707-50DGN?
  The maximum voltage that can be applied to the VCC pin of the TPS3707-50DGN is 12V. Exceeding this voltage can damage the device.
• Can the TPS3707-50DGN be used in a high-temperature environment?
  The TPS3707-50DGN 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 if operating in a high-temperature environment.
• How does the TPS3707-50DGN handle power-up and power-down sequences?
  The TPS3707-50DGN 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, and will keep the reset output asserted until the input voltage has fallen below the threshold voltage minus the hysteresis.
