Product details
Overview
The MAX6467US16D3+T from Analog Devices is a microprocessor supervisory reset circuit in SOT143-4 package, monitoring +1.8V supply with factory-trimmed 1.575V reset threshold (±1.5% at +25°C), 150ms minimum reset timeout, active-low open-drain RESET output, and edge-triggered manual reset input. It ensures reliable power-on reset and brownout detection in automotive-grade embedded systems.
For engineers reviewing the MAX6467US16D3+T datasheet, MAX6467US16D3+T pinout, MAX6467US16D3+T application, or MAX6467US16D3+T equivalent, this device delivers precision voltage monitoring, glitch-immune manual reset timing, low 3µA supply current at 1.8V, operation down to VCC = +1V, and AEC-Q100-qualified performance across –40°C to +125°C.
Technical Context
This supervisory IC implements a precision bandgap-based voltage reference for threshold detection, combined with analog comparators and digital one-shot timers to generate deterministic reset pulses. Its edge-triggered MR input uses internal debounce logic (150ms rising-edge holdoff) and ignores switch bounce, ensuring single-pulse assertion per button press.
The open-drain RESET output requires an external pullup and remains valid down to VCC = +1V, while the 150ms VCC reset timeout and MR timeout are factory-set via laser trimming. The device operates over 1.2V–5.5V supply range and features ±3% threshold accuracy over full automotive temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6315US16D3+T | Same SOT143-4 package, identical 1.575V threshold and 150ms timeout, but push-pull RESET output | Requires no external pullup; not suitable where wired-OR reset bus is used | Select when system needs active-drive high-state RESET and no shared reset lines |
| TLV803EB16DBVR | 1.6V threshold (vs. 1.575V), 200ms min timeout, 1.8V–6V supply, SOT-23-3 package | Smaller footprint but lacks MR input; only VCC reset functionality | Select when manual reset is unnecessary and board space is constrained |
Compared with MAX6467US16D3+T, MAX6315US16D3+T offers push-pull drive without external components but sacrifices wired-OR flexibility, while TLV803EB16DBVR reduces size and cost but removes manual reset capability entirely-making MAX6467US16D3+T optimal for space-tolerant designs requiring both precision threshold and edge-triggered MR.

FAQ
What is the exact reset threshold voltage of the MAX6467US16D3+T and how tightly is it specified?
The MAX6467US16D3+T has a factory-trimmed reset threshold of 1.575V, with ±1.5% tolerance at +25°C and ±3% over the full –40°C to +125°C operating range. This precision eliminates need for external calibration and ensures reliable detection of 1.8V supply droop within defined safety margins. The threshold is laser-trimmed during manufacturing and verified per AEC-Q100 test flow.
Does the MAX6467US16D3+T support manual reset, and how does its edge-triggered behavior work?
Yes, the MAX6467US16D3+T features an edge-triggered manual reset (MR) input that responds only to the falling edge of the MR signal. Upon detection, it asserts RESET low for a fixed 150ms one-shot pulse, ignoring subsequent MR transitions during that period and applying 150ms rising-edge debounce to prevent false triggers from switch bounce. This guarantees exactly one reset pulse per button press.
What type of RESET output does the MAX6467US16D3+T provide, and what design considerations apply?
The MAX6467US16D3+T provides an active-low open-drain RESET output, requiring an external pullup resistor to the appropriate logic rail (e.g., 1.8V or 3.3V). This configuration enables wired-OR reset buses and voltage-level translation. The output remains valid down to VCC = +1V, and leakage is limited to 1µA when not asserted-critical for low-power retention modes.
Is the MAX6467US16D3+T qualified for automotive applications, and what standards does it meet?
Yes, the MAX6467US16D3+T is AEC-Q100 qualified for automotive use, tested across –40°C to +125°C with validated reliability for thermal cycling, HTOL, and ESD. Its SOT143-4 package is RoHS-compliant (+T suffix), and the device meets stringent automotive requirements for reset timing accuracy, glitch immunity, and long-term parametric stability under vibration and temperature stress.
How much supply current does the MAX6467US16D3+T draw, and how does it scale with voltage?
The MAX6467US16D3+T draws only 3µA typical supply current at VCC = +1.8V, rising to 4µA at +2.5V, 6µA at +3.6V, and 7µA at +5.5V. This ultralow quiescent current enables multi-year operation from primary lithium batteries and makes the MAX6467US16D3+T ideal for always-on monitoring in portable and remote sensing applications.
