ISL6123IRZA - Renesas Electronics

Description: The Intersil ISL6123, ISL6124, ISL6125, ISL6126, ISL6127, ISL6128 and ISL6130 are integrated 4-channel controlled-on/controlled-off power-supply sequencers with supply monitoring, fault protection and a “sequence completed” signal (RESET). For larger systems, more than four supplies can be sequenced by simply connecting a wire between the SYSRESET pins of cascaded ICs. The ISL6125 uses four active open-drain outputs to control the on/off sequencing of four supplies. The other sequencers use a patented, micr

ISL6123IRZA Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power lines.
  • To ensure stability, use a minimum output capacitance of 10uF, and ensure that the output capacitor's ESR is less than 1 ohm. Also, avoid using ceramic capacitors with high ESL.
  • The ISL6123IRZA can handle input voltages up to 28V, but it's recommended to keep the input voltage below 24V for optimal performance and reliability.
  • The output voltage can be calculated using the formula: Vout = (R1/R2) * (1 + R3/R4) * Vref, where R1, R2, R3, and R4 are the resistors in the feedback network, and Vref is the internal reference voltage (1.25V).
  • The ISL6123IRZA can deliver up to 3A of output current, but it's recommended to keep the output current below 2.5A for optimal performance and reliability.
