MIC2033 High-Accuracy, High-Side, Fixed Current-Limit Power Switch Features General Description 5% Current-Limit Accuracy The MIC2033 is a high-side MOSFET power distribution switch that provides increased system Input Supply Range from 2.5V to 5.5V reliability, utilizing 5% current-limit accuracy. Low Quiescent Current: 100 A Typical (Switch ON) The MIC2033 has an operating input voltage range from 2.5V to 5.5V, is internally current-limited and has at 5V 75m Typical R DS(ON) thermal shutdown to protect the device and system. Current-Limit Options: 0.5A, 0.8A, 1A, and 1.2A The MIC2033 is offered with either active-high or Soft-Start Control via an External Capacitor active-low logic level enable input controls, has an Undervoltage Lockout (UVLO) open-drain fault status output flag with a built-in 32 ms Fast Response Time (10 s) to Short-Circuit delay that asserts low during over current or thermal Loads shutdown conditions. Fault Status Output Flag The MIC2033 is available in several different fixed Logic Controlled Enable (Active-High, Active-Low) current-limit options: 0.5A, 0.8A, 1A, and 1.2A. A capacitor-adjustable soft-start circuit minimizes inrush Thermal Shutdown current in applications where high capacitive loads are Pin Compatible with MIC2005 used. 6-Pin 2 mm x 2 mm Thin DFN and 6-Pin SOT-23 The MIC2033 is offered in both 6-pin SOT-23 and 6-pin Packages 2 mm x 2 mm thin DFN packages. The MIC2033 has Junction Temperature Range from 40C to an operating junction temperature range of 40C to +125C +125C.
