MIC2505-1YM

The MIC2505-1YM is a single integrated high-side Power Switch that consists of TTL compatible control/enable inputs, a charge pump and protected N-channel MOSFETs. The MIC2505 family can be used instead of separate high-side drivers and MOSFETs in many low-voltage applications. The MIC2505 family controls voltages ranging from 2.7 to 7.5V. A slow turn-on feature prevents high inrush current when switching capacitive loads. Within the device’s input range, outputs can be forced higher than the input voltage when disabled. 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. Overcurrent limiting is internally fixed and requires no external components. Open-load detection is active when the switch is off. When off, a normal load pulls the output pin low.
