Analog Devices Inc./Maxim Integrated MAX16164ANT0D+

Overview

MAX16164ANT0D+ from Analog Devices is a nanopower on/off controller with programmable sleep time, integrating a 200mA latched MOSFET power switch and configured by default for pushbutton-initiated wake-up. It operates from 1.7V to 5.5V, draws only 10nA in SHUTDOWN state, and supports I²C or resistor-based sleep time programming (100ms–24hr or infinite). It is used in battery-sealed IoT sensors requiring ultra-low quiescent current and robust pushbutton interface.

For engineers reviewing the MAX16164ANT0D+ datasheet, MAX16164ANT0D+ pinout, MAX16164ANT0D+ application, or MAX16164ANT0D+ equivalent, key selection criteria include its SHUTDOWN-first power-up behavior, ±60V pushbutton tolerance, 10nA shutdown IQ, I²C address configuration, and WLP-6 package compatibility with space-constrained portable designs.

Technical Context

The MAX16164ANT0D+ implements a deterministic finite-state machine with dedicated PB_WAIT, RES_CALC, SHUTDOWN, ACTIVE, and SLEEP_TIMER states. Its internal 50MΩ pulldown enables automatic I²C/resistor mode detection based on PB/SLP-to-GND resistance (>5.5MΩ → I²C mode).

Unlike the MAX16163, the MAX16164 remains in SHUTDOWN after power-up until a valid pushbutton press triggers wake-up; it does not assert OUT autonomously. Sleep timing is controlled either via external R_SLP (100ms–24hr) or I²C register writes (0x00–0x1F), with ±5% accuracy and 40–90ms hardware debounce.

FAQ

What is the default power-up behavior of the MAX16164ANT0D+?

The MAX16164ANT0D+ enters SHUTDOWN state immediately after power-up and keeps OUT deasserted until a valid pushbutton press is detected on the PB/SLP pin. This behavior ensures zero-load current during storage and shipping - a core requirement for battery-sealed devices. Unlike the MAX16163ANT0D+, it does not auto-assert OUT at startup.

How does the MAX16164ANT0D+ determine whether to use I²C or resistor programming?

The MAX16164ANT0D+ measures the resistance between the PB/SLP pin and GND during the RES_CALC state after power-up. If R_SLP > 5.5MΩ, it configures itself for I²C mode (SCL/CLR and SDA/INT become I²C pins); otherwise, it defaults to resistor mode (SCL/CLR becomes CLR, SDA/INT becomes INT). No external configuration pins are required.

What is the maximum load current supported by the MAX16164ANT0D+ OUT pin?

The MAX16164ANT0D+ supports up to 200mA continuous load current on the OUT pin, with a typical voltage drop of less than 30mV at 200mA and VCC = 3.3V. The output is a latched source driver - once asserted, it remains on until cleared by CLR (resistor mode) or I²C SHUTDOWN command (I²C mode).

Can the MAX16164ANT0D+ be used in automotive under-hood applications?

Yes - the MAX16164ANT0D+ is rated for -40°C to +125°C operating temperature and features ±60V tolerance on the PB/SLP pin, ±40kV HBM ESD protection, and robust pushbutton debounce. These characteristics make it suitable for under-hood sensors, tire pressure monitors, and other automotive edge nodes where thermal stress and electrical noise are present.

Is there a difference in PCB layout between MAX16164ANT0D+ and MAX16163ANT0D+?

No - MAX16164ANT0D+ and MAX16163ANT0D+ share identical pinout, package (WLP-6), and land pattern. They are pin-compatible and footprint-interchangeable. The functional difference is purely behavioral (SHUTDOWN-first vs. ACTIVE-first boot), requiring no layout change - only firmware or system-level timing logic adaptation.
