SGM2535
2.7V to 18V eFuse with True Reverse Blocking and Device Sleep Support for SSDs
The SGM2535 is a compact and rich power management eFuse power switch with a full range of protection functions. The device has a low power sleep mode in compliance with the SATA device sleep standard. Due to the wide device operating range, numerous basic DC bus voltages can be controlled by SGM2535. Since integrated back-to-back FETs enable bidirectional current regulation, the device is highly suitable for systems whose load side hold-up energy must not flow reversely to the failed power side.
Many programmed features like load, source, and device safety are included, such as over-current, SS ramp, and over-voltage and under-voltage thresholds. PG, nFAULT, and precise current monitor output are provided by the device for system status monitoring and downstream load control. SSD power management design is simplified by precise programmable under-voltage, over-voltage thresholds and the low IQ device sleep mode.
SGM2535 monitors VIN and VOUT to provide true reverse current blocking when VIN < VOUT - 10mV. In systems where the backup voltage is higher than the bus voltage, this function enables faster change to a boosted voltage rail.
The SGM2535 is available in a Green TQFN-3×4-20L package.
