Analog Devices Inc./Maxim Integrated MAX6715UTVDD3+

Overview

MAX6715UTVDD3+ from Maxim Integrated is a dual-voltage microprocessor supervisory IC monitoring VCC1 (primary supply) and VCC2 (secondary supply) with factory-trimmed reset thresholds, 210ms minimum reset timeout, push-pull active-low RST output, and manual reset input - used in multivoltage embedded systems to ensure reliable power-on reset and brownout protection.

For engineers reviewing the MAX6715UTVDD3+ datasheet, MAX6715UTVDD3+ pinout, MAX6715UTVDD3+ application, or MAX6715UTVDD3+ equivalent, this page delivers verified electrical specs, SOT23-6 package details, dual-supply monitoring behavior, reset timing validation, and real-world substitution guidance for industrial and telecom power management designs.

Technical Context

The MAX6715UTVDD3+ integrates two independent voltage comparators with ±1.5% threshold accuracy over temperature, a precision 210ms reset timeout timer, and a push-pull RST output referenced to VCC1. It guarantees valid reset assertion down to VCC1 or VCC2 = 0.8V and features immunity to sub-20µs VCC transients.

It supports manual reset via MR (internally pulled up to VCC1 with 50kΩ), asserts reset when either monitored supply falls below its threshold, and holds reset for the full timeout after all supplies recover - eliminating need for external RC timing networks or discrete supervisors.

Key Specifications

Pinout & Package

MAX6715UTVDD3+ is housed in a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), RoHS-compliant and lead-free (+T suffix). The compact footprint supports high-density PCB layouts in space-constrained applications such as set-top boxes and portable networking gear.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-voltage supervisory applications.

Compared with MAX6715UTVDD3+, MAX6316US46D3+ reduces functionality by removing VCC2 monitoring but matches timing and footprint, while TPS3808G33DBVR offers vendor-alternative single-rail supervision with higher current and open-drain output - neither replicates the dual-threshold, push-pull, low-I_CC combination of the MAX6715UTVDD3+.

FAQ

What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6715UTVDD3+?

The MAX6715UTVDD3+ has factory-trimmed thresholds: VCC1 = 4.625V (typical, ±1.5% over temperature) and VCC2 = 3.075V (typical, ±1.5%). These values are encoded in the "TV" and "DD" suffixes per Maxim's Reset Voltage Threshold Suffix Guide and are confirmed in the Electrical Characteristics table of the official datasheet.

Does the MAX6715UTVDD3+ support manual reset, and how is it implemented?

Yes, the MAX6715UTVDD3+ includes an active-low manual reset input (MR) on Pin 3, with an internal 50kΩ pullup resistor to VCC1. Driving MR low for ≥1µs forces reset assertion for the full 210ms timeout period. No external components are needed - the pin accepts TTL/CMOS logic levels and supports momentary switch interfacing directly to GND.

What package type and pin count does the MAX6715UTVDD3+ use?

The MAX6715UTVDD3+ uses a 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), RoHS-compliant and lead-free (indicated by the "+" suffix). Pin 6 is NC (no connect); functional pins are RST (1), GND (2), MR (3), VCC2 (4), VCC1 (5), and NC (6).

Is the reset output of the MAX6715UTVDD3+ push-pull or open-drain, and what are its drive capabilities?

The MAX6715UTVDD3+ features a push-pull, active-low RST output (Pin 1) referenced to VCC1. It sources ≥800µA at VOH ≥0.8×VCC1 and sinks ≥3.2mA at VOL ≤0.4V (VCC1 ≥4.5V), enabling direct connection to µP reset pins without external pullup resistors - unlike open-drain alternatives requiring external biasing.

How does the MAX6715UTVDD3+ behave when VCC1 or VCC2 drops below 0.8V?

The MAX6715UTVDD3+ guarantees correct reset output logic state only when VCC1 or VCC2 remains ≥0.8V. Below this level, reset behavior is not specified. For systems requiring valid reset down to 0V, Maxim recommends adding a 100kΩ pull-down from RST to GND - though this applies only to push-pull variants like the MAX6715UTVDD3+ and not open-drain versions.
