Analog Devices Inc./Maxim Integrated MAX16150CWT+T

Overview

MAX16150CWT+T 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 disposable electronics.

For engineers reviewing the MAX16150CWT+T datasheet, MAX16150CWT+T pinout, MAX16150CWT+T application, or MAX16150CWT+T equivalent, key selection considerations include its 50ms debounce / 16s shutdown timing profile, WLP-6 package footprint, ±15kV HBM ESD protection at PB_IN, and latch-retention behavior (OUT stays asserted after long press), distinguishing it from MAX16150A/B variants.

Technical Context

The MAX16150CWT+T implements a robust input protection architecture with internal pullup and ±60V tolerant PB_IN, enabling direct connection to mechanical switches in harsh environments. Its timing engine supports fixed 50ms debounce and 16s shutdown periods, with interrupt pulse durations of 32ms (after tDB) or 128ms (after tSO), both with ±5% accuracy.

It features dual-output logic: an active-high push-pull OUT capable of sourcing 20mA with <100mV dropout, and an active-low open-drain INT with programmable pulse width. The asynchronous CLR input forces OUT low but is locked out for 2×tINT after each OUT assertion to prevent spurious resets.

Key Specifications

Pinout & Package

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power management ICs for demanding industrial, medical, and automotive applications.

The MAX16150 family targets ultra-low-power system power control - specifically engineered for battery freshness sealing, disposable electronics, and ESD-prone human-interface applications where nanoscale quiescent current and ±60V switch tolerance are mandatory.

FAQ

What is the debounce time and shutdown period configured for MAX16150CWT+T?

The MAX16150CWT+T is factory-configured with a 50ms debounce time (t_DB) and a 16s shutdown period (t_SO). A pushbutton press exceeding 50ms asserts the latched OUT and triggers a 32ms INT pulse; a press exceeding 16s extends the INT pulse to 128ms while keeping OUT asserted - confirming its latch-retentive behavior per Table 1 in the MAX16150 datasheet.

Does MAX16150CWT+T support direct load driving, and what is its maximum output current?

Yes, MAX16150CWT+T supports direct load driving via its push-pull OUT pin, delivering up to 20mA with less than 100mV voltage drop across the output stage. This enables direct powering of low-current circuitry such as MCU enable inputs, small sensors, or bias rails - eliminating the need for an external MOSFET or regulator in space-constrained designs.

What package type is used for MAX16150CWT+T, and is it RoHS-compliant?

MAX16150CWT+T uses a 1mm × 1.5mm, 6-bump wafer-level package (WLP) with bottom-side solder bumps. It is RoHS-compliant and lead-free, indicated by the "+" in the part number suffix. The WLP footprint supports high-density PCB layouts and is compatible with standard reflow soldering processes per JEDEC J-STD-020.

How does the CLR input function on MAX16150CWT+T, and is there any timing restriction?

The CLR input on MAX16150CWT+T is an asynchronous active-low signal that forces the latched OUT to deassert immediately. However, after OUT assertion, CLR transitions are ignored for a lockout period equal to 2×t_INT (i.e., 64ms for short press, 256ms for long press) to prevent noise-induced resets during critical startup sequences.

What level of ESD protection does MAX16150CWT+T provide on the PB_IN pin?

MAX16150CWT+T provides ±15kV Human Body Model (HBM) ESD protection on the PB_IN pin - verified per JEDEC JS-001. This protection remains effective in all operating states (powered, unpowered, or shutdown), and the device continues functional operation post-ESD event without requiring power cycling - a critical reliability feature for handheld and industrial equipment interfaces.
