BD4827G-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.

BD4827G-TR Frequently Asked Questions (FAQs)

  • A good PCB layout for the BD4827G-TR should include a solid ground plane, wide power traces, and a thermal relief pattern under the IC to facilitate heat dissipation. ROHM provides a recommended PCB layout in their application notes.
  • To ensure stable operation with a high-ESR output capacitor, it's recommended to add a 1-10nF ceramic capacitor in parallel with the output capacitor to reduce the 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 IC. It's recommended to use a voltage divider or a level shifter if the enable signal is from a higher voltage domain.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency. ROHM provides a detailed calculation method in their application notes.
  • A low-ESR ceramic capacitor with a value of 4.7-10uF is recommended for the input capacitor. The capacitor should be placed close to the IC to minimize parasitic inductance and ensure stable operation.
