The recommended layout and placement for the TPS3823-25DBVRG4 can be found in the Texas Instruments application note 'TPS3823 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 of the TPS3823-25DBVRG4 is fixed at 2.5V, but it can be adjusted using an external resistor divider network connected to the VREF pin. The application note 'TPS3823 Reset Threshold Adjustment' (SLVAE05) provides a detailed explanation and calculation for adjusting the reset threshold voltage.
The maximum allowed capacitance on the VCC pin of the TPS3823-25DBVRG4 is 10uF. Exceeding this value may cause instability or oscillations in the device. It's recommended to use a ceramic capacitor with a value between 1uF to 4.7uF for optimal performance.
The TPS3823-25DBVRG4 is rated for operation up to 125°C, but it's essential to consider the device's thermal characteristics and ensure proper thermal management to prevent overheating. The device's power dissipation and thermal resistance (θJA) should be taken into account when designing for high-temperature applications.
Texas Instruments provides a troubleshooting guide for the TPS3823-25DBVRG4 in the application note 'TPS3823 Troubleshooting Guide' (SLVAE06). It covers common issues, such as incorrect reset timing, voltage monitoring, and power-up sequencing, and provides guidance on debugging and resolving these issues.
