BU931T Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the BU931T is 2.7V to 5.5V, with a typical voltage of 3.3V.
  • To ensure proper power-on and power-off, it's recommended to use a power-on reset (POR) circuit and a voltage supervisor to monitor the power supply voltage.
  • The maximum current rating for the BU931T's output pins is 20mA per pin, with a total current limit of 100mA for all output pins combined.
  • To ensure ESD protection, it's recommended to use a TVS (Transient Voltage Suppressor) diode or a dedicated ESD protection IC, such as the STMicroelectronics ESDAxx series, in conjunction with the BU931T.
  • For optimal performance, it's recommended to follow a star-topology layout, with the BU931T at the center, and to use short, direct traces for the power supply and output pins.
