BD4830G-TR - ROHM Semiconductor

Description: Standard Voltage Detectors: ROHM CMOS reset ICs provide low current consumption and high accuracy. 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.

BD4830G-TR Frequently Asked Questions (FAQs)

  • A recommended PCB layout for optimal thermal performance would be to have a large copper area on the bottom layer connected to the thermal pad of the IC, and to use thermal vias to dissipate heat to the top layer. Additionally, keeping the thermal pad away from other components and traces can help reduce thermal resistance.
  • To ensure stable operation with a high-ESR output capacitor, it's recommended to add a small ceramic capacitor (e.g. 1uF) in parallel with the output capacitor to improve the overall ESR. Additionally, ensuring the output capacitor is placed close to the IC and using a low-ESR capacitor can also help.
  • The maximum allowed voltage on the EN pin is VCC + 0.3V. Exceeding this voltage may cause damage to the IC.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout x ESL) / (Cout x fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
  • A recommended input capacitor value is 4.7uF to 10uF, and a type with low ESR and high ripple current rating, such as an X5R or X7R ceramic capacitor, is recommended.
