MCP73213T-A6SI/MF

The MCP73213T-A6SI/MF is Microchip’s six-pin voltage-monitoring/reset supervisor IC in a SOT-23-6 package (A6SI). It continuously monitors VDD and asserts a reset output to a microcontroller or other digital logic when the supply is out of range, providing a reliable power‑on/brown‑out reset without external components. The T/A6SI/MF designations relate to packaging (A6SI = 6‑pin SOT‑23) and RoHS/packaging variants (MF). The device offers low quiescent current and fast response, making it suitable for battery-powered or space-constrained designs. Typical use: connect VDD to the supply, ground to ground, and feed the reset output to the MCU’s reset line (or RESETn as configured). The MCP73213 family provides fixed-threshold supervision; choose the version with the appropriate threshold for your system. For exact thresholds, timing, current, and pinout, consult the MCP73213 datasheet.

Here are the typical features of the MCP73213T-A6SI/MF (Microchip):
- 6-pin SOT-23 package (A6SI) with MF lead-free/RoHS-compliant option.
- Low-dropout (LDO) voltage regulator suitable for battery-powered apps.
- Fixed-output and/or adjustable-output variants available.
- Enable/shutdown input for power-saving control.
- Ultra-low quiescent current (battery-friendly).
- Short-circuit protection and thermal shutdown for robustness.
- Reverse-current protection to prevent back-feeding when input is off.
- Stable with ceramic output capacitors; low-noise operation.
- Wide input/output operating range suitable for common rail voltages.
Note: exact voltage options, current capability, and precision depend on the specific variant. Please refer to the datasheet for exact electrical specs.

Pin count: 6 pins (SOT-23-6 package, A6SI/MF).
Function: Microcontroller supervisory/reset IC. It monitors the supply (VDD) and generates a reset signal (POR) for a microcontroller to ensure proper startup/shutdown behavior.
