MIC2505/2506  
Single 2A / Dual 1A / High-Side Switches  
General Description  
Features  
The MIC2505, MIC2505-1, MIC2505-2, and MIC2506 are  
single and dual integrated high-side power switches that  
consist of TTL compatible control/enable inputs, a charge  
pump, and protected N-channel MOSFETs. The MIC2505/6  
family can be used instead of separate high-side drivers and  
MOSFETs in many low-voltage applications.  
• Low MOSFET on resistance to 2.7V  
30mΩ typical at 5V (MIC2505-series)  
35mΩ typical at 3.3V (MIC2505-series)  
75mΩ typical at 5V (each MIC2506 output)  
80mΩ typical at 3.3V (each MIC2506 output)  
• 2.7V to 7.5V input  
• 110µA typical on-state supply current  
• 1µA typical off-state supply current  
• Output can be forced higher than input (off-state)  
• Current limit  
• Thermal shutdown  
• 2.5V undervoltage lockout (UVLO)  
• Open-load detection  
(MIC2505BN/M and MIC2506BN/M only)  
• Open-drain fault flag  
• 5ms (slow) turn-on and fast turnoff  
• Logic-level control/enable input  
The MIC2505/6 family controls voltages ranging from 2.7V to  
7.5V. The MIC2505-series can deliver at least 2A continuous  
current while the MIC2506 can deliver at least 1A continuous  
current from each output. A slow turn-on feature prevents  
high inrush current when switching capacitive loads. The  
internal control circuitry is powered from the same 2.7V to  
7.5V. Within the device’s input range, outputs can be forced  
higher than the input voltage when disabled.  
Multipurpose open-drain fault flag outputs indicate overcur-  
rent limiting, open-load detection (except MIC2505-1 and -2  
versions), thermal shutdown, or undervoltage lockout for  
each channel.  
Applications  
Overcurrent limiting is internally fixed and requires no exter-  
nal components.  
• USB Power Distribution  
• 3.3V and 5V power management  
• PC Card card inrush limiting switch  
• Hot plug-in power supplies  
• Battery-charger circuits  
Open-load detection is active when the switch is off. When  
off, a normal load pulls the output pin low. If the load is open,  
an optional, external, high-value resistor pulls the output pin  
high, triggering the fault flag. MIC2505-1 and -2 versions are  
tailoredtoUniversalSerialBus(USB)applicationsanddonot  
include open-load detection.  
Thermal shutdown turns off the output if the die temperature  
exceeds approximately 135°C. If enabled, the switch auto-  
matically restarts when the temperature falls 10°C.  
Undervoltage lockout (UVLO) shuts off the output if the  
supply drops below 2.3V typical and reenables the output  
when the supply exceeds 2.5V typical.
