MIC2505/2506
Single 2A / Dual 1A / High-Side Switches
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.
