Analog Devices Inc./Maxim Integrated MAX6462XR26+T

Overview

MAX6462XR26+T from Maxim Integrated is a precision ultra-low-power voltage detector IC designed for battery and power-supply monitoring in space-constrained, low-quiescent-current systems. It features a factory-set 2.600V lower trip threshold (VTH−), ±2.5% threshold accuracy over −40°C to +125°C, 1.0µA supply current at 3.6V, and 17µs propagation delay. It is used in portable medical devices and cellular phones to ensure reliable power-on reset and brownout detection.

For engineers reviewing the MAX6462XR26+T datasheet, MAX6462XR26+T pinout, MAX6462XR26+T application, or MAX6462XR26+T equivalent, this page delivers verified functional identity, SC70-3 package mapping, threshold hysteresis behavior, output stage configuration (push-pull active-high), and real-world design trade-offs versus alternatives.

Technical Context

The MAX6462XR26+T implements a precision bandgap reference with internally trimmed resistor networks to set its 2.600V VTH− threshold and 2.730V VTH+ upper threshold (5% hysteresis). Its comparator-based architecture asserts output high when VCC falls below VTH− and holds assertion until VCC rises above VTH+, eliminating external components for threshold setting.

This device belongs to the MAX6461–MAX6466 family's voltage detector subgroup (not µP supervisory), so it lacks internal reset timeout - output transitions are purely threshold-driven with no minimum pulse width. Its push-pull active-high output stage delivers VOH ≥ 0.8×VCC at up to 8mA source current and VOL ≤ 0.4V at 9mA sink current.

Key Specifications

Pinout & Package

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog and mixed-signal ICs for power management, sensing, and interface applications in demanding environments.

The MAX6461–MAX6466 family was engineered specifically for ultra-low-power voltage monitoring in battery-critical systems, emphasizing minimal quiescent current, factory-trimmed accuracy, and integration to eliminate discrete support components.

FAQ

What is the exact voltage threshold of MAX6462XR26+T?

The MAX6462XR26+T has a factory-set lower trip threshold (VTH−) of 2.600V at +25°C, with guaranteed tolerance of ±2.5% over −40°C to +125°C. Its upper trip threshold (VTH+) is 2.730V (5% hysteresis), calculated as VTH− × 1.05. These values are confirmed in Table 1a and Table 1b of the official datasheet.

Does MAX6462XR26+T include a reset timeout function?

No, MAX6462XR26+T does not include an internal reset timeout period. As a member of the MAX6461/MAX6462/MAX6463 voltage detector subgroup, its output responds instantaneously to threshold crossing (17µs propagation delay) without minimum pulse width enforcement. For timeout functionality, consider MAX6465XR26+T instead.

What is the output configuration of MAX6462XR26+T?

MAX6462XR26+T features a push-pull active-high output stage. When VCC ≥ VTH+, OUT is driven high (VOH ≥ 0.8×VCC); when VCC ≤ VTH−, OUT is driven low (VOL ≤ 0.4V at 9mA). This eliminates the need for an external pull-up resistor and ensures defined logic levels at all times.

Can MAX6462XR26+T operate down to 1.2V supply?

Yes, MAX6462XR26+T is fully specified to operate from VCC = 1.2V to 6.0V. Its 1.0µA supply current and functional performance (including threshold accuracy and propagation delay) are guaranteed across this full range per Absolute Maximum Ratings and Electrical Characteristics tables in the datasheet.

Is MAX6462XR26+T pin-compatible with other MAX646x variants in SC70-3?

Yes, all SC70-3 packaged MAX6461–MAX6466 variants (e.g., MAX6461XR26+T, MAX6463XR26+T) share identical pinout: Pin 1 = OUT, Pin 2 = GND, Pin 3 = VCC. However, output logic polarity and presence of timeout differ - MAX6462XR26+T is active-high push-pull, while MAX6463XR26+T is active-low open-drain and MAX6461XR26+T is active-low push-pull.
