AP1201  
Single-Channel Power Distribution Switch  
ꢀFeatures  
ꢀGeneral Description  
The AP1201 series are integrated high-side power  
switch with enable, flag functions and adjustable  
current-limit 0.7A to 1.25A, optimized for  
self-powered and bus-powered Universal Serial  
Bus (USB) applications. The AP1201 series support  
the following USB requirements: each switch  
channel supplies up to 700mA as required by USB  
downstream devices; the switch’s low on-resistance  
meets USB voltage drop requirements; fault current  
is limited to typically 900mA~1.25A; and a flag  
output is available to indicate fault conditions to the  
local USB controller. Soft start eliminates the  
momentary voltage drop on the upstream port that  
may occur when the switch is enabled in  
bus-powered applications.  
- 100mΩ typical on-resistance  
- 2.7V to 5.5V input voltage  
- Adjustable current-limit 0.7A to 1.25A  
(AP1201A/C)  
- Fixed current-limit (1.25A) for AP1201B  
- Fault flag with internal delay circuit  
- 1μA typical off-state supply current  
- 65μA typical on-state supply current  
- Output can be forced higher than input (off-state)  
- Thermal shutdown  
- 2.4V typical under voltage lockout (UVLO)  
- Slow turn-on (soft-start) and fast turn-off  
- Enable Active-High or active-Low  
- SOT23-5L, SOT23-6L and SOT89-5L packages  
Additional features include thermal shutdown to  
prevent catastrophic switch failure from high-current  
loads, under voltage lockout (UVLO) to ensure that  
the device remains off unless there is a valid input  
voltage present, and 3.3V and 5V logic compatible  
enable inputs.
