The open-drain, active-low output lets multiple supervisors share a common pull-up resistor on a wired-OR reset bus — a common topology in multi-rail systems where any undervoltage must force a system-wide reset. ## Temperature range and package fit Housed in the 3-lead SC-70 (SOT-323) package, the 0.65mm pitch and 2.0mm × 2.1mm footprint fit densely populated boards where a SOT-23 would crowd the passives around a processor's reset pin. ## Active production, no cross-reference on record No official pin-compatible second source or manufacturer cross-reference is documented for this exact 4.38V threshold variant in the SC-70-3 package.","metaTitle":"MIC803-44D2VC3-TR Simple Reset IC, 4.38V Threshold, SC-70-3","metaDescription":"Microchip MIC803-44D2VC3-TR supervisor IC, active-low open-drain output, 4.38V threshold, 20ms reset timeout, SC-70-3, -40°C to 125°C.
