EM5210
2A Single Load Switch with Reverse Voltage Protection for
Low Voltage Rail
General Description
Applications
The EM5210 is a small, low RON load switch with controlled
turn on. The device contains an N-channel MOSFET that can
operate over an input voltage range of 1.2 V to 5.5 V. The
switch is controlled by an on/off input (ON), which is capable
of interfacing directly with low-voltage control signals. The
EM5210 is active high enable.

The EM5210 contains a 150-Ω on-chip load resistor for quick
output discharge when the switch is turned off. The rise time
of the device is internally controlled in order to avoid inrush
current. An internal reverse voltage comparator disables the
power-switch when the output voltage (VOUT) is driven
higher than the input (VIN) to quickly (20μs typ) stop the flow
of current towards the input side of the switch. Reverse
current is always active, even when the power-switch is
disabled. Additionally, under-voltage lockout (UVLO)
protection turns the switch off if the input voltage is too low.
The EM5210 is available in a small, space-saving 6-pin
SOT23-6 package and is characterized for operation over the
free-air temperature range of –40°C to 85°C.
