MIC2505/6

Single 2A/Dual 1A High-Side Switches

Features

General Description

• Low MOSFET On-Resistance to 3.0V

- 30 mΩ Typical at 5V (MIC2505 Series)

- 35 mΩ Typical at 3.3V (MIC2505 Series)

- 75 mΩ Typical at 5V (Each MIC2506 Output)

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.

- 80 mΩ Typical at 3.3V (Each MIC2506 Out-

put)

• 3.0V to 7.5V Input

The MIC2505/6 family controls voltages ranging from

3.0V 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 3.0V to 7.5V. Within the

device’s input range, outputs can be forced higher than

the input voltage when disabled.

• 110 µA Typical On-State Supply Current

• 1 µA 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 (MIC2505YN/M and

MIC2506YN/M Only)

Multipurpose open-drain fault flag outputs indicate

overcurrent limiting, open-load detection (except

MIC2505-1 and -2 versions), thermal shutdown, or

undervoltage lockout for each channel.

• Open-Drain Fault Flag

• 5 ms (Slow) Turn-On and Fast Turn-Off

• Logic-Level Control/Enable Input

Overcurrent limiting is internally fixed and requires no

external components.

Applications

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.

• USB Power Distribution

• 3.3V and 5V Power Management

• PC Card Inrush Limiting Switch

• Hot Plug-In Power Supplies

• Battery Charger Circuits

Thermal shutdown turns off the output if the die

temperature exceeds approximately 135°C. If enabled,

the switch automatically restarts when the temperature

falls 10°C.

Undervoltage lockout (UVLO) shuts off the output if the

supply drops below 2.3V typical and re-enables the

output when the supply exceeds 2.5V typical.
