Typical Application


The SY20806A is a small, low RON, single channel load switch with controlled slew rate. The device contains an N-channel MOSFET that can operate over an input voltage range of 1.05 V to 5.5 V and can support a maximum continuous current of 2 A. The switch is controlled by an on and off input, which is capable of interfacing directly with low-voltage control signals.

The small size and low RON makes the device ideal for being used in space constrained, battery powered applications. The wide input voltage range of the switch makes it a versatile solution for many different voltage rails. The controlled rise time of the device greatly reduces inrush current caused by large bulk load capacitances, thereby reducing or eliminating power supply droop.

The SY20806A further reduces the total solution size by integrating a 143Ω pull-down resistor for quick output discharge when the switch is turned off.

The SY20806A is available in a small, space-saving 0.78mm×0.78mm, 0.4-mm pitch, 0.5-mm height 4-pin CSP package. The device is characterized for operation over the free-air temperature range of –40°C to +105°C.
