Analog Devices Inc./Maxim Integrated MAX16150AWT+

Overview

MAX16150AWT+ from Maxim Integrated is a nanoPower pushbutton on/off controller with integrated switch debouncer, latched output, and one-shot interrupt generator. It accepts ±60V pushbutton inputs, delivers 20mA latched output with <100mV drop, consumes ≤20nA standby current, and operates from +1.3V to +5.5V across –40°C to +125°C - enabling battery freshness sealing and ultra-low-power system power control in portable medical sensors.

For engineers reviewing the MAX16150AWT+ datasheet, MAX16150AWT+ pinout, MAX16150AWT+ application, or MAX16150AWT+ equivalent, this page provides verified timing parameters (50ms debounce, 8s shutdown), ESD rating (±15kV HBM), package mapping (6-bump WLP), pin-level circuit roles, and validated alternatives for low-power enable/control designs.

Technical Context

The MAX16150AWT+ implements asynchronous switch detection with internal pull-up on PB_IN, fixed 50ms debounce and 8s shutdown timing, and dual-output behavior: OUT latches high on valid press and deasserts only on extended press (>tSO), while INT generates a 32ms pulse on tDB-exceeding closure or 128ms pulse on tSO-exceeding closure. Its robust input stage includes overvoltage clamping and ±15kV HBM ESD protection independent of supply state.

Operation requires no external components beyond VCC bypass; CLR provides asynchronous reset with 2×tINT lockout window after OUT assertion, and both OUT (push-pull) and INT (open-drain) drive directly into light loads or MCU interrupt inputs without level-shifting. The device remains functional post-ESD event without latchup or power cycle.

Key Specifications

Pinout & Package

MAX16150AWT+ uses a 1mm × 1.5mm, 6-bump wafer-level package (WLP) with bottom-side bump layout. Pin assignment follows standard WLP orientation (bump side down).

Compared with MAX16150AWT+, MAX16150BWT+ offers identical form factor and ultra-low power but different long-press behavior (hold-to-remain-ON vs. hold-to-OFF), while TPL92012DSQR trades ESD robustness, voltage tolerance, and standby current for lower unit cost and simpler timing - making it unsuitable for medical or industrial deployment.

FAQ

What is the debounce time and shutdown period for MAX16150AWT+?

The MAX16150AWT+ has a fixed 50ms debounce time (tDB) and 8s shutdown period (tSO). A PB_IN low pulse ≥50ms latches OUT high and triggers a 32ms INT pulse; a pulse >8s deasserts OUT and extends INT to 128ms. These values are factory-trimmed and not user-adjustable.

Can MAX16150AWT+ drive a 15mA load directly without external FETs?

Yes. The MAX16150AWT+ OUT pin delivers 20mA with <100mV voltage drop across its full 1.3V–5.5V supply range, making it suitable for direct driving of low-current loads such as op-amps, sensors, or MCU peripherals - confirmed in Electrical Characteristics Table (VOL specification).

Does MAX16150AWT+ require external components for basic operation?

No. Only a 0.1μF ceramic capacitor between VCC and GND is required for stable operation. No external pull-ups, resistors, or timing capacitors are needed - the debounce, shutdown, and interrupt timers are fully internal and factory-calibrated.

How does the CLR input behave during power-up or after OUT assertion?

The CLR input is ignored when OUT is deasserted. After OUT asserts, CLR is locked out for 2×tINT (64ms for MAX16150AWT+) to prevent spurious resets during transient conditions. This lockout window is specified in the Electrical Characteristics table under "CLR Lockout Time".

Is MAX16150AWT+ compatible with 1.8V logic systems?

Yes. MAX16150AWT+ operates down to +1.3V supply and specifies VOH = VCC – 0.02V at 1.3V/500μA, ensuring reliable high-level signaling into 1.8V logic inputs. Its VIH threshold is 80% VCC at low VCC, guaranteeing clean recognition of 1.8V signals when VCC ≥ 2.25V.
