Analog Devices Inc./Maxim Integrated MAX16150AWT+T

Overview

MAX16150AWT+T from Maxim Integrated is a nanoPower pushbutton on/off controller with integrated switch debouncer, latched output, and one-shot interrupt generator. It operates from +1.3V to +5.5V, draws ≤20nA standby current, tolerates ±60V at PB_IN, and delivers 20mA latched output with <100mV drop - enabling direct load control or regulator enable in ultra-low-power portable instruments and disposable electronics.

For engineers reviewing the MAX16150AWT+T datasheet, MAX16150AWT+T pinout, MAX16150AWT+T application, or MAX16150AWT+T equivalent, key selection criteria include debounce/shutdown timing (50ms/8s), INT pulse duration (32ms or 128ms), ±15kV HBM ESD rating, WLP package footprint, and latch behavior (deasserts on long press).

Technical Context

The MAX16150AWT+T implements asynchronous switch detection with internal pull-up on PB_IN, fixed 50ms debounce and 8s shutdown timing, and dual-mode interrupt generation: standard pulse after tDB and extended 4× pulse after tSO. Its latched OUT drives loads directly or enables external regulators, while INT provides active-low open-drain system signaling.

Robust input protection includes ±60V continuous voltage tolerance and ±15kV HBM ESD on PB_IN, with no latchup after ESD events. The device supports cold-start initialization via PB_IN or CLR and features 2×tINT lockout window after OUT assertion to prevent spurious CLR resets.

Key Specifications

Pinout & Package

MAX16150AWT+T uses a 1mm × 1.5mm, 6-bump wafer-level package (WLP) with bottom-side solder bumps. Pin mapping follows JEDEC MO-220 standard for WLP devices.

FAQ

What is the debounce timing configuration for MAX16150AWT+T?

The MAX16150AWT+T has a fixed 50ms debounce time (tDB) and 8s shutdown period (tSO). These values are factory-programmed and not adjustable. A PB_IN low pulse ≥50ms causes OUT to assert and generate a 32ms INT pulse; a pulse ≥8s causes OUT to deassert and triggers a 128ms INT pulse. This timing is confirmed in Table 1 of the MAX16150 datasheet and applies exclusively to the MAX16150A variant, which MAX16150AWT+T implements.

Does MAX16150AWT+T support direct load driving, and what is its maximum output current?

Yes, MAX16150AWT+T supports direct load driving via its latched OUT pin, delivering up to 20mA with less than 100mV voltage drop at VCC = 3.3V. This capability allows it to power microcontrollers, sensors, or LEDs without an external regulator. The specification is guaranteed across -40°C to +125°C and is measured under ISINK = 1.6mA (VOL = 0.4V) and ISOURCE = 20mA (VOH = VCC – 0.1V), per the Electrical Characteristics table in the MAX16150 datasheet.

What package type does MAX16150AWT+T use, and how does it differ from MAX16150AUT+T?

MAX16150AWT+T uses a 1mm × 1.5mm, 6-bump wafer-level package (WLP) with bottom-side solder bumps (package code W60C1+2). In contrast, MAX16150AUT+T uses a 6-pin thin SOT23 package (U6+1). Both share identical pin functions and electrical specifications, but the WLP offers 60% smaller footprint and lower profile - critical for ultra-compact designs like wearable diagnostics. Land pattern requirements differ significantly; refer to Maxim Application Note 1891 for WLP layout guidelines.

How does the CLR input behave during normal operation of MAX16150AWT+T?

The CLR input on MAX16150AWT+T is asynchronous and forces OUT low when pulled below VIL (30% VCC). However, after OUT asserts, CLR is ignored for a lockout period of 2×tINT (64ms or 256ms depending on press duration). This prevents spurious resets during interrupt processing. When OUT is deasserted, CLR has no effect. This behavior is documented in the Pin Description and Operation sections of the MAX16150 datasheet and is consistent across all temperature ranges.

What ESD protection level does MAX16150AWT+T provide, and on which pins?

MAX16150AWT+T provides ±15kV Human Body Model (HBM) ESD protection specifically on the PB_IN pin, as verified per JEDEC JS-001. Other pins (VCC, GND, OUT, INT, CLR) meet standard ±2kV HBM. The ±15kV rating on PB_IN eliminates need for external TVS diodes in high-ESD environments such as industrial handhelds or clinical devices. This specification is guaranteed and tested - not typical - and appears in the Absolute Maximum Ratings and Electrical Characteristics tables of the MAX16150 datasheet.
