Analog Devices Inc./Maxim Integrated MAX6410BS46-T

Overview

MAX6410BS46-T from Maxim Integrated is an ultra-low-power, active-high push-pull voltage detector optimized for battery and power-supply monitoring in portable electronics. It features a factory-trimmed 4.63V threshold (±2.5% over –40°C to +85°C), 500nA supply current, manual reset input (MR), and guaranteed valid output down to VCC = 1.0V - enabling reliable brownout detection in Li+-based systems and low-voltage microcontroller supervision.

For engineers reviewing the MAX6410BS46-T datasheet, MAX6410BS46-T pinout, MAX6410BS46-T application, or MAX6410BS46-T equivalent, this device is selected for precision reset generation in space-constrained, battery-sensitive designs where low quiescent current, temperature-stable threshold accuracy, and MR-initiated system recovery are critical.

Technical Context

The MAX6410BS46-T uses a precision bandgap reference comparator with internal trimming to deliver ±2.5% threshold accuracy across –40°C to +85°C. Its active-high push-pull output asserts logic high when VCC falls below 4.63V and remains valid down to 1.0V supply, supporting deep brownout detection in low-voltage embedded systems.

It incorporates a manual reset input (MR) with internal 50kΩ pullup, TTL/CMOS-compatible logic levels, and 1µs minimum pulse width requirement. Immunity to fast VCC transients is achieved via built-in glitch rejection (100ns) and propagation delay filtering (200ns MR-to-OUT).

Key Specifications

Pinout & Package

FAQ

What is the exact reset threshold voltage of the MAX6410BS46-T?

The MAX6410BS46-T has a nominal reset threshold of 4.63V, with tolerance of ±2.5% over the full operating temperature range (–40°C to +85°C). This value is factory-trimmed and specified in Table 1 of the datasheet under suffix "46". The MAX6410BS46-T achieves this accuracy using an internal bandgap reference and laser trimming during production.

Does the MAX6410BS46-T require external components for basic operation?

No, the MAX6410BS46-T operates autonomously with no external components required for core functionality. Its factory-trimmed threshold, internal MR pullup, and push-pull output eliminate the need for resistive dividers, pullup resistors, or capacitors - though a 0.1µF VCC bypass capacitor is recommended for noise immunity. The MAX6410BS46-T is designed for drop-in integration into space-constrained layouts.

Can the MAX6410BS46-T operate reliably at VCC = 1.2V?

Yes, the MAX6410BS46-T is fully specified to operate down to VCC = 1.2V (minimum per Electrical Characteristics table) and guarantees valid output logic states down to VCC = 1.0V. This ensures deterministic reset assertion during deep brownout events, such as Li+ battery discharge below 3.0V, making the MAX6410BS46-T suitable for low-voltage supervisory roles where other detectors fail.

What is the function of the MR pin on the MAX6410BS46-T?

The MR (Manual Reset) pin on the MAX6410BS46-T is an active-low input with internal 50kΩ pullup to VCC. Driving MR low forces the OUT pin high (active state) regardless of VCC level, enabling external system reset initiation. If unused, MR may be left floating or tied to VCC. The MAX6410BS46-T requires a minimum 1µs pulse width on MR for reliable assertion, supporting both GPIO and mechanical switch interfaces.

Is the MAX6410BS46-T pin-compatible with other devices in the MAX6406–MAX6411 family?

Yes, all members of the MAX6406–MAX6411 family, including the MAX6410BS46-T, share identical UCSP-4 pinout (GND/A1, VCC/A2, OUT/B1, MR/B2) and footprint. However, output logic polarity differs: MAX6410BS46-T is active-high push-pull, while MAX6409BS46-T is active-low push-pull and MAX6411BS46-T is active-low open-drain - requiring schematic review before substitution.
