MIC2074 Datasheet | Micrel Semiconductor

Description Features The MIC2073/2074 are high-side MOSFET switches optimized for general-purpose power distribution requiring circuit protection. The MIC2073/2074 are internally current limited and have thermal shutdown for protecting the device and load. The MIC2074 offers “smart” shutdown that reduces current consumption in fault mode. When a fault occurs due to thermal shutdown, the output is latched off. The MIC2074s’ output will be reset, enabling the output, either by removing the load or toggling the ENABLE pin. Both devices employ soft-start circuitry that minimizes inrush current in applications where highly capacitive loads are employed. A fault status output flag is asserted during overcurrent or thermal shutdown conditions. Transient faults are internally filtered. The MIC2073/2074 are available in an 8-pin SOIC. - 115 mΩ typical RBDS(ON) at 5.0 V - 210 mΩ maximum RBDS(ON) at 5.0 V - 2.7 V to 5.5 V operating range - 500 m A minimum continuous current per channel - Short circuit protection with thermal shutdown - Thermally isolated channels - Fault status flag (FLGA/B) separate for each channel - 3ms fault flag delay (TD) eliminates false assertions - UVLO (Undervoltage Lockout) - Reverse current flow blocking (no “body diode”) - Circuit breaker mode (MIC2074) - Logic-patible inputs - Soft-start circuit - Low quiescent current - Pin patible with the MIC2026/2076 All support documentation can be found on Micrel’s web site at: .micrel..
