Diodes Incorporated AP2297x Single Channel Load Switches

Diodes Incorporated AP2297x Single Channel Load Switches provide controlled turn-on and an active output discharge path in an ultra-compact X1-WLB1909-8 package. The Diodes Inc. AP2297x contains an N-channel MOSFET that can operate over an input voltage range of 0.65V to 3.6V and switch currents up to 4A. An integrated charge pump biases the NMOS switch to achieve a minimum switch ON resistance (RON). The switches are controlled by an on-and-off input (ON) capable of interfacing directly with low-voltage control signals.

The AP2297x includes thermal shutdown when the junction temperature is above the threshold, turning the switch off. The switches turn on again when the junction temperature stabilizes to a safe range. The AP2297x have a 150Ω on-chip resistor for quick output discharge when the switch is disabled to avoid any unknown states caused by a floating supply to the downstream load.
