MIC6315-26D3UY

MIC6315-26D3UY is a Microchip (formerly Micrel) voltage detector/supervisor IC. It monitors the supply voltage (Vcc) and generates a reset signal for microcontrollers or other digital logic when Vcc falls below a fixed threshold or during power-up/power-down, helping ensure safe startup and operation.
Key points
- Fixed-threshold voltage detector in a compact package (variant-specific value given in the datasheet)
- Low quiescent current suitable for battery-powered designs
- Fast reset assertion/de-assertion with protection against voltage transients
- Directly usable for MCU reset inputs; commonly used for brown-out/power supervision
- Available in small surface-mount packages
Typical applications
- Microcontroller and processor reset generation
- Brown-out and power-on-reset in embedded systems
- Safe startup/shutdown signaling for digital logic and memory
Note
- Exact threshold, pinout, timing specs, and packaging are device-specific; consult the MIC6315-26D3UY datasheet for precise values. If you’d like, I can fetch the datasheet or provide a quick spec summary.

Key features of MIC6315-26D3UY (voltage supervisor/reset IC):
- Fixed 2.6 V reset threshold (26).
- Active-low reset output (push-pull) to reliably reset MCU/logic.
- Very low quiescent current in normal operation.
- Power-on reset with guaranteed reset pulse until Vcc settles.
- Manual reset input for external force reset (MR).
- Wide operating supply range (typical 2.7 V–5.5 V).
- Temperature range suitable for industrial use (commonly -40°C to +125°C).
- 8-pin package (D3UY code), surface-mount compatible.
Note: For exact electrical specs (tolerances, pulse width, exact voltage ranges, and package details), please consult the latest datasheet.

SOT-23-3 (SC-70-3) surface-mount package.

- Pin count: 3 pins (SOT-23-3/SC-70-3 package)
- Function: Voltage detector/reset supervisor with a 2.6 V threshold. It monitors Vcc and provides an active-low reset output to a microcontroller when Vcc falls below threshold (and releases reset when Vcc is above threshold). No external components required for basic operation.

Manufacturer: Microchip Technology (the Micrel line). Microchip is an American multinational semiconductor company that designs and manufactures integrated circuits, including microcontrollers, memory, and analog/timing devices.

MIC6315-26D3UY is a voltage supervisor that generates a reset signal when the supply falls below its 2.6V threshold. Applications: MCU/MPU reset and brown-out protection; power-on reset for embedded controllers; battery-powered/portable devices (IoT, wearables, handhelds); power-management and reset signaling in consumer electronics and automotive electronics.
