DESCRIPTION
The high-side switch is a 110mΩ N-channel MOSFET. 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.
