MIC2073/2074 Dual-Channel Power Distribution Switch General Description Features The MIC2073/2074 are high-side MOSFET switches • 115 mΩ typical RB DS(ON) at 5.0 V optimized for general-purpose power distribution requiring • 210 mΩ maximum RB DS(ON) at 5.0 V circuit protection. • 2.7 V to 5.5 V operating range The MIC2073/2074 are internally current limited and have • 500 mA minimum continuous current per channel thermal shutdown for protecting the device and load. • Short circuit protection with thermal shutdown The MIC2074 offers “smart” shutdown that reduces current • Thermally isolated channels consumption in fault mode. When a fault occurs due to thermal shutdown, the output is latched off. The • Fault status flag (FLGA/B) separate for each channel MIC2074s’ output will be reset, enabling the output, either • 3ms fault flag delay (TD) eliminates false assertions by removing the load or toggling the ENABLE pin. • UVLO (Undervoltage Lockout) Both devices employ soft-start circuitry that minimizes • Reverse current flow blocking (no “body diode”) inrush current in applications where highly capacitive loads • Circuit breaker mode (MIC2074) are employed. • Logic-compatible inputs A fault status output flag is asserted during overcurrent o
