SY28846B - Load Switch

General Description

The SY28846B protection switch is a compact power management device with a full suite of protection functions, including a low-power device sleep (DevSleep) mode.

The wide operating range allows control of many popular DC BUS voltages.

Key Features

  • including overcurrent, dVo/dt ramp, over-voltage, and under-voltage thresholds using very few external components. The device provides PGOOD, /FLT and precise current monitor output for system status monitoring and downstream load control. The precise programmable and low IQ DevSleep mode simplifies SSD power management design. The SY28846B provides true reverse current blocking by monitoring VIN < (VOUT - 25mV). This function supports swift change over to a boosted voltage energy storage eleme.

SY28846B 2.7V-18V Load Switch With Reverse Blocking General Description The SY28846B protection switch is a compact power management device with a full suite of protection functions, including a low-power device sleep (DevSleep) mode. The wide operating range allows control of many popular DC BUS voltages. Integrated back-to-back MOSFETs provide bidirectional current control, making the device well-suited for systems with load-side energy reservoirs that must not drain back to a failed supply BUS. The device provides many programmable features, including overcurrent, dVo/dt ramp, over-voltage, and under-voltage thresholds using very few external components. The device provides PGOOD, /FLT and precise current monitor output for system status monitoring and downstream load control.
