For an input voltage up to 40 V the TLF4277 provides an adjustable output voltage in a range from 5 V up to 12 V. The integrated current monitor function is a unique feature that provides diagnosis and system protection functionality. Fault conditions such as over temperature and output over voltage are monitored and indicated at the current sense output. The maximum output current limit of the device is adjustable to provide additional protection to the connected load. Summary of Features Integrated Current Monitor Adjustable Current Limitation Adjustable Output Voltage Overvoltage Detection Output Current up to 200 mA Very Low Current Consumption Very Low Dropout Voltage Wide Input Voltage Range up to 40 V Reverse Polarity Protection Short Circuit Protected Overtemperature Shutdown Automotive Temperature Range -40 °C ≤ T j ≤ 150 °C Green Product (RoHS and WEEE compliant) AEC Qualified Benefits Robust Protection Features Wide Input Operation and Temperature Range Integrated Current Monitor Potential Applications Automotive Antenna Supply Family Overview For an overview of other available options in this family please click here.
