Analog Devices Inc./Maxim Integrated MAX6382XR24D6+T

Overview

MAX6382XR24D6+T from Maxim Integrated is a push-pull active-high microprocessor supervisory circuit with factory-set 2.40V reset threshold, 560ms minimum VCC reset timeout, and guaranteed operation down to VCC = 1.0V. It monitors single supply voltage in low-power embedded systems and asserts RESET high during brownout or power-up sequencing. Designed for space-constrained applications, it consumes only 3μA at +1.8V and operates across –40°C to +125°C.

For engineers reviewing the MAX6382XR24D6+T datasheet, MAX6382XR24D6+T pinout, MAX6382XR24D6+T application, or MAX6382XR24D6+T equivalent, key selection criteria include its active-high push-pull output logic, ±2.5% reset threshold accuracy over temperature, 3-pin SC70 package footprint, and compatibility with 1.8V–5.0V supply rails in battery-powered and automotive-qualified designs.

Technical Context

The MAX6382XR24D6+T implements a precision bandgap-based voltage comparator with internal 2.40V reference and a monostable timeout circuit triggered on VCC falling below threshold. Its reset assertion is synchronized to VCC transitions without external components, and output state remains valid even as VCC drops to 1.0V - enabling reliable initialization in deep brownout conditions.

No manual reset (MR) input or auxiliary RESET IN pin is present in this variant; it is a dedicated single-supply monitor with fixed timing and threshold. The device uses BiCMOS process technology and meets AEC-Q100 requirements when ordered with /V suffix, though MAX6382XR24D6+T itself is RoHS-compliant and rated for –40°C to +125°C operation.

Key Specifications

Pinout & Package

FAQ

What is the exact reset threshold voltage of MAX6382XR24D6+T?

The MAX6382XR24D6+T has a factory-set nominal reset threshold of 2.40V, with tolerance of ±2.5% over the full operating temperature range (–40°C to +125°C). This value is confirmed in the Reset Thresholds table of the datasheet, where suffix "24" corresponds to 2.40V (min 2.34V, max 2.46V at +25°C). The MAX6382XR24D6+T maintains this accuracy without external calibration.

Does MAX6382XR24D6+T include a manual reset input (MR)?

No, MAX6382XR24D6+T does not feature a manual reset input. Per the Selector Guide and Pin Configurations, MR is only present on MAX6384/MAX6385/MAX6386/MAX6390 variants. The MAX6382XR24D6+T is a dedicated single-supply supervisor with RESET and VCC/GND only - no MR pin, no RESET IN, and no NC terminals beyond the three functional pins.

What is the minimum VCC voltage at which MAX6382XR24D6+T guarantees valid RESET output?

The MAX6382XR24D6+T guarantees correct RESET output logic state down to VCC = 1.0V, as explicitly stated in the Electrical Characteristics table and Applications Information section. This ensures deterministic reset behavior during deep brownout events where other supervisors may enter undefined states. The MAX6382XR24D6+T remains fully functional and predictable even as supply voltage collapses toward 1.0V.

Which package type and footprint does MAX6382XR24D6+T use?

MAX6382XR24D6+T uses the 3-pin SC70 package (outline number 21-0075, land pattern 90-0208), designated by package code X3+2. Its dimensions are 1.25mm × 0.85mm with 0.65mm pitch. This compact footprint matches industry-standard SC70 layouts and is compatible with reflow soldering per JEDEC J-STD-020. The MAX6382XR24D6+T has no 6-pin μDFN variant - only the 3-pin SC70 option.

Is MAX6382XR24D6+T qualified for automotive applications?

The MAX6382XR24D6+T is RoHS-compliant and rated for –40°C to +125°C operation, but it is not AEC-Q100 qualified by default. Automotive qualification requires the /V suffix (e.g., MAX6382XR24D6/V+T), which denotes specific test screening and traceability. The MAX6382XR24D6+T lacks the /V marking and is intended for industrial and commercial applications unless explicitly ordered with automotive-grade ordering codes.
