MAX891L：限流型、高边P沟道开关，带有热关断
低电阻p沟道开关，为系统和USB提供可调节的、精确的限流保护
The MAX891L/MAX892L smart, low-voltage, P-channel, MOSFET power switches are intended for high-side load-switching applications. These switches operate with inputs from 2.7V to 5.5V, making them ideal for both 3V and 5V systems. Internal current-limiting circuitry protects the input supply against overload. Thermal-overload protection limits power dissipation and junction temperatures. The MAX891L/MAX892L's maximum current limits are 500mA and 250mA, respectively. The current limit through the switch is programmed with a resistor from SET to ground. When the switch is on, the quiescent supply current is a low 13µA. When the switch is off, the quiescent current decreases to 0.1µA. The MAX891L/MAX892L are available in 8-pin µMAX® packages.
