The SY28810A is a 2.8mΩ, single-channel load switch with a controlled and adjustable turn-on and integrated Power Good (PG) indicator.

The device contains an N-channel MOSFET that can operate over an input voltage range of 0.6V to 5.5V and can support a maximum continuous current of 10A. The wide input voltage range and high current capability enable the device to be used in various applications. The low ON resistance of 2.8mΩ minimizes the voltage drop across the load switch, effectively reducing power loss.

The device's controlled rise time can help mitigate the inrush current associated with large bulk load capacitances, effectively minimizing or eliminating power supply droop. The design flexibility is enhanced through the adjustable slew rate which can be configured using an external capacitor, CSST, allowing for a trade-off between inrush current and power-up timing requirements. Additionally, the integrated PG indicator informs the system of the load switch status, aiding in seamless power sequencing.

The SY28810A is available in a compact DFN 2mm×3mm-10pin package with an integrated thermal pad, enabling efficient dissipation of high power. The device is designed for operation across a wide temperature range, from -40°C to +105°C in free-air conditions.
