Analog Devices Inc./Maxim Integrated MAX16150AUT+T

Overview

MAX16150AUT+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 battery-powered portable instruments and disposable electronics.

For engineers reviewing the MAX16150AUT+T datasheet, MAX16150AUT+T pinout, MAX16150AUT+T application, or MAX16150AUT+T equivalent, this page provides verified timing parameters (50ms debounce, 8s shutdown), ESD rating (±15kV HBM), package mapping (6-pin SOT23), and functional distinctions among MAX16150 variants for reliable power-control system design.

Technical Context

The MAX16150AUT+T implements asynchronous switch detection with internal pull-up on PB_IN, fixed 50ms debounce and 8s shutdown timing (per Table 1, MAX16150A variant), and generates a 32ms INT pulse for standard closures or 128ms for long presses (>tSO). Its latch logic deasserts OUT upon extended PB_IN closure, enabling hardware-initiated shutdown without MCU intervention.

Robust input protection includes ±60V continuous voltage tolerance and ±15kV HBM ESD rating on PB_IN, with no latchup after ESD events. The active-high push-pull OUT drives loads directly up to 20mA, while open-drain INT requires external pull-up and asserts low for precise interrupt timing synchronized to switch events.

FAQ

What is the debounce time of the MAX16150AUT+T?

The MAX16150AUT+T has a fixed debounce time of 50ms, as specified in Table 1 of the datasheet for the MAX16150A variant. This timing rejects mechanical switch bounce while ensuring reliable detection of intentional user presses. The value is factory-trimmed and guaranteed over -40°C to +125°C; deviation is ±20% across temperature and voltage.

Does the MAX16150AUT+T support long-press shutdown functionality?

Yes-the MAX16150AUT+T implements long-press shutdown with an 8s shutdown period (tSO). When PB_IN remains low beyond 8s, the latched OUT deasserts and the INT output pulses low for 128ms (4× nominal 32ms), signaling the host MCU to execute a controlled shutdown sequence without software debounce logic.

Can the MAX16150AUT+T drive a 15mA load directly?

Yes-the MAX16150AUT+T latched output delivers 20mA with less than 100mV voltage drop at VCC = 3.3V, making it suitable for directly powering 15mA microcontrollers, sensors, or RF modules. At lower VCC (e.g., 1.8V), output current capability scales down per VOH/VOL specs, so verify load compliance at minimum operating voltage.

What is the maximum voltage allowed on the PB_IN pin of the MAX16150AUT+T?

The PB_IN pin of the MAX16150AUT+T supports continuous voltages from -60V to +60V relative to GND, as stated in Absolute Maximum Ratings. This robustness eliminates the need for external clamping diodes or resistors when interfacing with unregulated or high-noise switch circuits in industrial or automotive-adjacent environments.

Is the MAX16150AUT+T pin-compatible with other MAX16150 variants?

The MAX16150AUT+T shares identical 6-pin SOT23 pinout and electrical behavior with MAX16150BUT+T and MAX16150CUT+T, differing only in internal timing parameters (debounce/shutdown intervals) and latch behavior. All SOT23 variants use the same footprint, allowing drop-in replacement where timing requirements align with the specific variant's specification.
