Analog Devices Inc./Maxim Integrated MAX6376XR24-T

Overview

MAX6376XR24-T from Maxim Integrated is an ultra-low-power, active-high push-pull voltage detector designed for precision supply monitoring in battery-powered systems. It features a factory-trimmed 2.40V threshold (±2.5% over temperature), 500nA supply current, and operates down to 1V VCC. It asserts a logic-high output when VCC falls below threshold and is used in portable equipment power sequencing and Li+-battery voltage supervision.

For engineers reviewing the MAX6376XR24-T datasheet, MAX6376XR24-T pinout, MAX6376XR24-T application, or MAX6376XR24-T equivalent, key selection criteria include reset threshold accuracy, ultra-low quiescent current, active-high push-pull output drive capability, transient immunity, and SC70-3 package compatibility with space-constrained PCB layouts.

Technical Context

The MAX6376XR24-T integrates a precision bandgap reference, comparator, and laser-trimmed resistive divider to set its 2.40V detection threshold without external components. Its internal architecture ensures stable operation across -40°C to +85°C with ±2.5% threshold accuracy and 40ppm/°C tempco.

It employs propagation delay filtering to reject fast VCC transients-capable of ignoring negative-going glitches up to 200µs at 40mV overdrive-while delivering 6.3µs typical falling-edge response. The push-pull output drives high (VOH ≥ 0.8×VCC) and low (VOL ≤ 0.4V) with 500µA source/1.2mA sink capability at VCC ≥ 2.1V.

FAQ

What is the exact reset threshold voltage of the MAX6376XR24-T?

The MAX6376XR24-T has a factory-trimmed nominal reset threshold of 2.40V, with guaranteed accuracy of ±2.5% over the full operating temperature range (-40°C to +85°C). This value is laser-trimmed during production and does not require external calibration or resistor adjustment. The MAX6376XR24-T achieves this precision using an integrated bandgap reference and trimmed resistive divider, ensuring consistent performance across units and over time.

Does the MAX6376XR24-T require external components to operate?

No, the MAX6376XR24-T requires no external components to perform its voltage detection function. It integrates a precision bandgap reference, comparator, and factory-trimmed resistor network internally. A bypass capacitor on VCC is recommended for noise suppression, but no external resistors, capacitors, or pull-up devices are needed - simplifying design, reducing BOM cost, and improving reliability. This self-contained operation is confirmed in the device's General Description and Applications Information sections.

What is the output configuration of the MAX6376XR24-T and how does it interface with an MCU?

The MAX6376XR24-T features an active-high push-pull output, meaning it drives logic-high (VOH ≥ 0.8×VCC) when VCC falls below 2.40V and logic-low (VOL ≤ 0.4V) otherwise. This allows direct connection to standard CMOS reset inputs without external pull-up resistors. The output can source 500µA and sink 1.2mA, meeting typical MCU reset pin drive requirements. This interface behavior is explicitly defined in the Pin Description and Electrical Characteristics tables for the MAX6376XR24-T.

How does the MAX6376XR24-T handle power supply transients?

The MAX6376XR24-T incorporates built-in transient immunity to reject short-duration negative-going VCC glitches. According to its Typical Operating Characteristics, it ignores transients up to 200µs in duration when the overdrive (VTH – VCC) is 40mV. This filtering prevents false resets caused by switching noise or load transients. The MAX6376XR24-T achieves this through internal propagation delay control and hysteresis (100mV), ensuring robust operation in electrically noisy environments.

What package and pinout does the MAX6376XR24-T use, and is it compatible with automated assembly?

The MAX6376XR24-T uses the SC70-3 package (2.0mm × 2.1mm × 0.95mm), with pin 1 = GND, pin 2 = OUT, and pin 3 = VCC - matching the top-view diagram in the datasheet. It is supplied in tape-and-reel format and fully compatible with standard SMT pick-and-place equipment and reflow profiles for lead-free or leaded soldering. The SC70-3 footprint is documented in Maxim's Package Outline SOT23 L.EPS and supported by industry-standard land patterns.
