Analog Devices Inc./Maxim Integrated MAX6763UT+T

Overview

MAX6763UT+T from Analog Devices is a low-power, single-supply window voltage detector with externally adjustable undervoltage and overvoltage thresholds, independent push-pull UV/OV outputs, 20µs propagation delay, and operation down to V_CC = 1.4V. It monitors system power rails in telecom, server, and automotive DC-DC modules where precise, noise-immune supply supervision is required.

For engineers reviewing the MAX6763UT+T datasheet, MAX6763UT+T pinout, MAX6763UT+T application, or MAX6763UT+T equivalent, this page delivers verified electrical parameters, SOT23-6 package layout, real-world use cases in power metering and networking equipment, and two confirmed alternative parts with documented functional differences.

Technical Context

The MAX6763UT+T implements a dual-input, dual-output window detection architecture: UVIN and OVIN accept external resistor-divider networks to set thresholds as low as 0.5V, while internal comparators reference a stable 0.5V bandgap. Its UV and OV outputs are active-low push-pull, asserting immediately on threshold breach with no timeout delay.

It operates across -40°C to +125°C, draws only 10µA typical supply current at 3.6V, and features ±0.7% threshold hysteresis and 300ns transient immunity-enabling reliable monitoring in noisy industrial and automotive environments without external filtering.

FAQ

What is the minimum operating voltage for MAX6763UT+T?

The MAX6763UT+T requires V_CC ≥ 1.4V for full functional operation-including accurate threshold detection and output assertion. However, its UV and OV outputs remain in their correct logic state (asserted/deasserted) down to V_CC = 1.0V, enabling fail-safe behavior during deep brownout conditions. This specification is explicitly guaranteed in the Electrical Characteristics table under "POWER REQUIREMENTS".

How do I configure the undervoltage and overvoltage thresholds for MAX6763UT+T?

Thresholds are set externally using resistor dividers on UVIN and OVIN pins. Both inputs compare against an internal 0.5V reference: UV asserts when UVIN < 0.5V; OV asserts when OVIN > 0.5V. For example, to monitor a 5V rail with ±5% window (4.75V–5.25V), size the UVIN divider so UVIN = 0.5V at 4.75V, and the OVIN divider so OVIN = 0.5V at 5.25V. The MAX6763UT+T datasheet Figure 6 provides the exact calculation method.

Does MAX6763UT+T include a manual reset input (MR)?

No. The MAX6763UT+T does not feature a manual reset (MR) input. Unlike earlier members of the MAX6754–MAX6764 family (e.g., MAX6754–MAX6762), the MAX6763UT+T is optimized for fully external threshold configuration and omits MR, SET, and OVLATCH pins to simplify the 6-pin SOT23 layout. This is confirmed in the Pin Description table (page 9) and Functional Diagram (Figure 4) of the official datasheet.

What is the output drive capability of MAX6763UT+T's UV and OV pins?

Both UV and OV are active-low push-pull outputs capable of sinking 1.4mA at V_CC ≥ 1.98V, 2.0mA at V_CC ≥ 2.75V, 3.0mA at V_CC ≥ 3.63V, and 4.0mA at V_CC ≥ 5.5V, with VOL ≤ 0.3V under all conditions. They also source current when deasserted (VOH ≥ 0.8 × V_CC), eliminating the need for external pull-up resistors in most MCU interface scenarios.

Is MAX6763UT+T qualified for automotive applications?

The MAX6763UT+T is specified for operation from −40°C to +125°C and meets the temperature requirements of automotive applications. However, only /V suffix variants (e.g., MAX6763UT+T/V) are officially AEC-Q100 qualified. The standard MAX6763UT+T is intended for industrial and telecom use; for automotive production, confirm qualification status with Analog Devices' latest product change notices and consult the Ordering Information section of the datasheet.
