PRODUCT DESCRIPTION
The AMS2026 is a dual power distribution switch intended for applications where heavy capacitive loads and short-circuits
are likely to be encountered. The high-side switch is a 110m
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 AMS2026 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. Continuous heavy overloads and short circuits will increase
the power dissipation in the switch; 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 AMS2026 is offered in the 8 lead SOIC package and the 8 lead PDIP package.
