BD45295G-TR - ROHM Semiconductor

Description: Voltage Detector with Fixed Delay Time: ROHM's BD45xxxG and BD46xxxG series of reset ICs utilize CMOS processes for low current consumption and high accuracy. The built-in counter timer delay circuit eliminates the need to set the delay time via external capacitor. The extensive lineup includes both Nch Open Drain and CMOS output types in a wide range of detection voltages (from 2.3V to 4.8V, in 0.1V steps), enabling selection of the ideal solution based on customer requirements. A total of 156 models are o

BD45295G-TR Frequently Asked Questions (FAQs)

  • ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • To ensure stable operation, ROHM recommends using an output capacitor with a low ESR (Equivalent Series Resistance) and a capacitance value between 10uF to 100uF. Additionally, a 1uF ceramic capacitor in parallel with the output capacitor can help improve stability.
  • The maximum allowed voltage on the EN (Enable) pin is 6V. Exceeding this voltage may damage the device.
  • The BD45295G-TR is rated for operation up to 105°C. However, ROHM recommends derating the output current and voltage to ensure reliable operation at high temperatures. Consult the datasheet for specific derating guidelines.
  • To troubleshoot oscillations or instability issues, check the PCB layout for proper thermal design, ensure the output capacitor is properly selected, and verify that the input voltage is within the recommended range. Also, check for any noise or ripple on the input voltage and ensure that the device is not overheating.
