MIC2514

MIC2514 IttyBitty® Integrated High-Side Switch General Description The MIC2514 is an integrated high-side power switch that consists of a TTL compatible input and protected Pchannel MOSFET. The MIC2514 can be used instead of a separate high-side driver and MOSFET in many lowvoltage applications. The MIC2514 switches voltage ranging from 3V to 13.5V and delivers more than 400mA continuous current. A slow turn-on feature prevents high inrush current when switching capacitive loads. The internal control circuitry is powered from the unswitched 3V to 13.5V input. Current limiting is internally fixed at approximately 1.9A and requires no external components. Thermal shutdown turns off the output if the die temperature exceeds approximately 170°C. The MIC2514 is available in the 5-pin SOT-23-5 package with a temperature range of –40°C to +85°C.
