UCD9112RHBT datasheet by Texas Instruments

UCD9112RHBT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a thermal relief pattern on the top layer to improve heat dissipation. A minimum of 2 oz copper thickness is recommended for the top layer.
• How do I ensure accurate voltage monitoring with the UCD9112RHBT?
  To ensure accurate voltage monitoring, it's essential to use a high-precision voltage reference, such as the TPS76701, and to follow the recommended layout and routing guidelines for the voltage sense lines. Additionally, consider using a low-noise, low-impedance power supply to minimize voltage drops.
• What is the maximum allowed voltage on the VDD pin?
  Although the datasheet specifies a maximum VDD voltage of 5.5V, it's recommended to limit the voltage to 5V or less to ensure reliable operation and prevent damage to the device.
• How do I configure the UCD9112RHBT for a specific application?
  Texas Instruments provides a UCD9112RHBT Evaluation Module (EVM) and a Graphical User Interface (GUI) software tool to simplify configuration and evaluation. The GUI allows users to configure the device, monitor performance, and adjust settings for their specific application.
• What is the recommended method for powering down the UCD9112RHBT?
  To power down the UCD9112RHBT, it's recommended to use the EN pin to disable the device. This ensures a controlled shutdown and prevents damage to the device or other components in the system.
