BD5229G-TR - ROHM Semiconductor

Description: Voltage Detector with Adjustable Delay Time: CMOS processes are utilized to develop high precision, low current consumption CMOS reset ICs that allow arbitrary setting of the delay time. The extensive lineup includes both Nch Open Drain and CMOS output types in a wide range of detection voltages (from 2.3V to 6.0V, in 0.1V steps), enabling selection of the ideal solution based on customer requirements. In addition, the entire series is of course both lead-free and RoHS-compliant.

BD5229G-TR Frequently Asked Questions (FAQs)

  • A good PCB layout for the BD5229G-TR should include a large copper area for heat dissipation, with multiple vias connecting the top and bottom layers to reduce thermal resistance. A minimum of 2oz copper thickness is recommended.
  • To ensure stable operation with a high-ESR output capacitor, it's recommended to add a 1-2nF ceramic capacitor in parallel with the output capacitor to reduce the overall ESR. Additionally, the output capacitor should be placed close to the IC to minimize parasitic inductance.
  • The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the internal circuitry. It's recommended to use a voltage divider or a level shifter if the control signal is higher than 6V.
  • While the BD5229G-TR is rated for operation up to 105°C, it's recommended to derate the output current and voltage to ensure reliable operation in high-temperature environments. Consult the datasheet for derating guidelines.
  • To troubleshoot oscillations or instability issues, check the PCB layout for any signs of parasitic inductance or capacitance. Ensure that the input and output capacitors are properly decoupled, and the feedback network is properly compensated. Consult the datasheet for recommended component values and layout guidelines.
