APL3520A/B/C/D
USB Dual Power-Distribution Switches
Features
General Description
• 70mΩ High Side MOSFET
• Continuous Current
-APL3520A/B: 1.5A
-APL3520C/D: 1A
• Wide Supply Voltage Range: 2.7V to 5.5V
• Current Limit and Short-Circuit Protections
• Over-Temperature Protection
• Deglitched Fault Indication Output
The APL3520 series of power switches are designed for
USB applications. The 70mΩ N-channel MOSFET power
switch satisfies the voltage drop requirements of USB
specification.
The protection features include current-limit protection,
short circuit protection, and over-temperature protection.
The device limits the output current at current limit thresh-
old level, and when V drops below 1.5V, the devices
OUT
limit the current to a lower and safe level. The OTP limits
