General Description

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.
