PRODUCT DESCRIPTION
The AMS2027 is a power distribution switch intended for application where heavy capacitive loads and short-circuits are
likely to be encountered. The high-side switch is a 110mΩ N-channel MOSFET. The switch is controlled by a logic enable
input compatible with 3V and 5V logic and is available in active-high or active-low enable. The internal charge pump,
designed to control the power switch rise and fall time to minimize current surges during switching, also provides the gate
drive. Requiring no external components the charge pump allows operation from supplies as low as 3.3V. When an overload
or a short circuit is encountered the AMS2027 limits the output current to a safe level by switching into a constant-current
mode and the overcurrent logic output error flag is set to a low. The power dissipation in the switch will be increased by
continuous heavy overloads and short circuits; this will cause the junction temperature to rise. The thermal protection circuit
shuts the power switch off to prevent damage. Once the device has cooled sufficiently, it will turn on automatic. An under
voltage lock-out is provided to insure that the power switch is in the Off state at start-up.
The AMS2027 is offered in the 8 lead SOIC package and the 8 lead PDIP package and is rated operational over a -40°C to
85°C temperature range.
