BQ76PL536APAPR datasheet by Texas Instruments

BQ76PL536APAPR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the BQ76PL536APAPR?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a decoupling capacitor (e.g., 10uF) close to the device's power pins.
• How do I ensure accurate voltage measurements with the BQ76PL536APAPR?
  Use a high-impedance voltage source (e.g., a voltage divider) and a low-noise analog signal path. Ensure the input voltage is within the specified range (0-5V). Use a filter capacitor (e.g., 10nF) to reduce noise.
• What is the recommended calibration procedure for the BQ76PL536APAPR?
  Perform a self-calibration by applying a known voltage (e.g., 2.5V) to the input pins and reading the output code. Use the calibration data to adjust the internal gain and offset registers. Refer to the datasheet for specific calibration procedures.
• How do I handle overvoltage protection for the BQ76PL536APAPR?
  Use external overvoltage protection (OVP) circuits, such as a voltage clamp or a zener diode, to limit the input voltage to the specified maximum (5.5V). Ensure the OVP circuit is designed to respond quickly to overvoltage events.
• What is the recommended power-up sequence for the BQ76PL536APAPR?
  Power up the device in the following sequence: VCC, AVCC, and then the input voltage. Ensure the power supplies are stable and within the specified voltage ranges before applying the input voltage.
