MIC2505/2506

General Description

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.

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.

Overcurrent limiting is internally fixed and requires no exter-

nal components.

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

tailored to Universal Serial Bus (USB) applications and do not

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.
