Key Features
- Single-channel voltage supervisor with 3.1 V reset threshold in a tiny 4-pin SC70 package for space-constrained designs
- Ultra-low power consumption suitable for battery-powered applications requiring continuous voltage monitoring
- Manual reset input and active-low reset output ensure reliable microprocessor startup and brown-out recovery
Applications
The MAX6389XS31D2+T is used in battery-powered portable electronics, industrial sensors, and embedded microcontroller systems where reliable power-on reset and brown-out detection at 3.1 V are critical. Its compact SC70 footprint makes it ideal for handheld devices and IoT nodes with constrained board space. System designers use this supervisor to ensure microprocessors restart correctly after voltage dips or cold-start conditions.

Frequently Asked Questions
What reset threshold voltage does MAX6389XS31D2+T monitor and how does it protect the system?
The MAX6389XS31D2+T monitors supply voltage against a 3.1 V threshold and asserts an active-low reset output whenever VCC drops below this level. This protects microprocessors and logic circuits from erratic behavior during brown-out events, ensuring the system remains in a known reset state until voltage recovers stably.
Which package does MAX6389XS31D2+T use and why is it advantageous for compact PCB designs?
MAX6389XS31D2+T comes in a 4-pin SC70 package, one of the smallest available for supervisory ICs, measuring approximately 2 mm x 1.25 mm. This enables integration into handheld devices, wearables, and IoT nodes where board space is limited to just a few square millimeters per component.
How does MAX6389XS31D2+T compare to a standard voltage supervisor without manual reset?
Unlike basic supervisors, the MAX6389XS31D2+T includes a manual reset input pin that lets a host processor or external circuit force a system reset independent of supply voltage. Combined with a 3.1 V threshold monitoring across 1 channel, this provides design flexibility for systems requiring both automatic and software-triggered reset capability within the same tiny SC70 outline.
