Analog Devices Inc./Maxim Integrated MAX6410BS40+T

Overview

MAX6410BS40+T from Maxim Integrated is an ultra-low-power, active-high push-pull voltage detector designed for system supply monitoring in battery-powered devices. It features a factory-trimmed 4.00V threshold (±2.5% over -40°C to +85°C), 500nA supply current at 3V, guaranteed valid output down to VCC = 1.0V, and integrated manual reset input with 50kΩ internal pullup. It is used to assert reset signals during brownout conditions in portable electronics.

For engineers reviewing the MAX6410BS40+T datasheet, MAX6410BS40+T pinout, MAX6410BS40+T application, or MAX6410BS40+T equivalent, key selection criteria include its 4.00V detection threshold, active-high push-pull output logic, UCSP-4 package compatibility, and immunity to sub-100ns VCC transients - all critical for low-power microcontroller supervisory design.

Technical Context

The MAX6410BS40+T implements a precision bandgap reference comparator with hysteresis of 9.5mV, enabling stable trip-point behavior despite noise. Its detector circuit ignores fast negative-going VCC transients up to duration limits defined by threshold overdrive (e.g., ≤200µs for 100mV overdrive).

It supports manual reset assertion via MR pin, which internally pulls up to VCC and requires only a momentary ground connection. Output remains asserted as long as MR is low or VCC falls below 4.00V, ensuring deterministic reset hold timing in embedded systems.

FAQ

What is the exact reset threshold voltage of the MAX6410BS40+T?

The MAX6410BS40+T has a factory-trimmed nominal reset threshold of 4.00V, with tolerance of ±2.5% over the full operating temperature range of –40°C to +85°C. This value is confirmed in Table 1 of the official datasheet and applies specifically to the "S40" suffix variant of the MAX6410BS series. The MAX6410BS40+T maintains this specification without requiring external calibration.

Does the MAX6410BS40+T require external components to operate?

No, the MAX6410BS40+T requires no external components for basic operation. Its precision bandgap reference, comparator, and 50kΩ internal MR pullup resistor are fully integrated. Unlike open-drain alternatives, its active-high push-pull output eliminates the need for an external pullup resistor, reducing BOM count and PCB area - a key advantage confirmed in the device's Features section and Electrical Characteristics table.

What package type and dimensions does the MAX6410BS40+T use?

The MAX6410BS40+T uses a 4-bump, 2mm × 2mm chip-scale package (UCSP-4) with bottom-mounted solder bumps. This package is documented in the "Package Information" section and Pin Configuration diagram of the datasheet. Its footprint is 70% smaller than SC70, and mechanical drawings confirm 0.5mm bump pitch and 45-mil (1.14mm) body size - verified on Maxim's official package outline EPS file.

Can the MAX6410BS40+T operate reliably at very low supply voltages?

Yes, the MAX6410BS40+T guarantees correct output logic state down to VCC = 1.0V, as specified in the Absolute Maximum Ratings and Electrical Characteristics tables. This ensures the reset signal remains valid during deep brownout or battery exhaustion - a critical capability explicitly called out in the General Description and validated across –40°C to +85°C.

How does the manual reset (MR) pin function on the MAX6410BS40+T?

The MR pin on the MAX6410BS40+T is an active-low input with an internal 50kΩ pullup to VCC. Pulling MR low asserts the active-high OUT signal regardless of VCC level; OUT remains asserted as long as MR is held low. When unused, MR may be left floating or tied to VCC. This behavior is detailed in the "Manual Reset Input" section and confirmed in the Pin Description table.
