TPS3831G12DQNT Frequently Asked Questions (FAQ)

  • The recommended layout and placement for the TPS3831G12DQNT can be found in the Texas Instruments application note 'TPS3831 Layout and Placement Guidelines' (SLVAE04). It provides guidance on component placement, routing, and thermal considerations to ensure optimal performance and reliability.

  • The reset threshold voltage (V_RST) can be calculated using the formula: V_RST = V_REF x (1 + R1/R2), where V_REF is the internal reference voltage (1.2V typical), R1 is the resistor connected between the V_RST pin and V_CC, and R2 is the resistor connected between the V_RST pin and GND. The datasheet provides more information on how to select the correct resistor values for your application.

  • The maximum allowed voltage on the V_CC pin is 6.5V. Exceeding this voltage can cause damage to the device. It's essential to ensure that the voltage on the V_CC pin does not exceed the recommended maximum rating.

  • The TPS3831G12DQNT has a built-in power-on reset (POR) circuit that ensures the device is in a known state during power-up. The POR timing can be adjusted by selecting the appropriate capacitor value on the V_RST pin. The datasheet provides more information on how to calculate the POR timing and select the correct capacitor value for your application.

  • The TPS3831G12DQNT is rated for operation up to 125°C (TJ). However, it's essential to consider the device's thermal characteristics, such as the junction-to-ambient thermal resistance (RθJA), when designing for high-temperature applications. Ensure that the device is properly heatsinked and that the operating temperature is within the recommended range.
