MIC6315-26D3UY

MIC6315-26D3UY is a fixed-threshold voltage supervisor from Microchip (Micrel) that provides a reliable reset signal for microcontrollers. It monitors Vcc and asserts its reset output when supply falls below a 2.6 V threshold; when Vcc rises above the threshold, the reset output is released after a short internal delay to ensure proper startup. The device offers low quiescent current and a small RoHS-compliant package (suffix D3UY). Typical applications include MCU/SoC reset supervision and brown-out protection. For exact electrical details (supply range, reset delay, output drive, and package specifics), consult the datasheet.

Equivalents (2.6 V reset supervisor) from major vendors:
- TI: TPS3800/TPS3810 family (2.6 V variants)
- Maxim: MAX809/MAX810 (2.63 V)
- Microchip: MCP1316/MCP1317 (2.6 V option)
- ON Semiconductor: NCP301/NCP302 series (2.6–2.7 V options)
Note: verify exact threshold, hysteresis, reset delay, and package when cross‑replacing.

Here are the key features of MIC6315-26D3UY (2.6V version):
- Fixed 2.6V reset threshold (MIC6315-26 variant) with specified hysteresis for clean reset release
- Power-on reset ensures MCU stays in reset until Vcc is above threshold
- Very low quiescent current (typical ~1 µA at moderate Vdd)
- Push-pull reset output (active-low RESET) capable of driving several mA
- 8-pin D3/UY package (compact, RoHS-compliant)
- Wide operating temperature range suitable for many applications
- Input/output protection and noise immunity suitable for brown-out protection
- Intended for microcontroller reset and system monitoring in low-voltage/battery-powered designs
Note: Always consult the latest datasheet for exact electrical specs, tolerances, drive, and packaging details.

- Pin count: 8 pins (8‑pin package)
- Function: Microprocessor supervisory/reset IC. Monitors Vcc and asserts a reset output when the supply drops below the 2.6 V threshold (variant 26); releases reset once the voltage stabilizes. Output is an active-low reset signal.

Manufacturer: Microchip Technology (the MIC6315 line originated with Micrel and was folded into Microchip after the Micrel acquisition in 2015).
What kind of company: An American multinational semiconductor company that designs and manufactures analog, power-management, microcontroller, and memory integrated circuits for embedded systems.
