DESCRIPTION

· The MAX22520 is a 24V line driver designed for industrial binary sensors, featuring a one-time programmable (OTP) analog interface for signal conditioning.

· It includes an integrated linear regulator providing a programmable 3.3V or 5V low-noise supply for analog sensing circuits.

· The driver output (DO) is configurable via the Maxim 1-Wire protocol and OTP interface, supporting normally-open, normally-closed, high-side (PNP), low-side (NPN), or push-pull configurations.

· The device offers robust protection against hot-plug events, surges, reverse polarity, short circuits, and ESD strikes.

· It operates from a 4.75V/8V to 36V supply and is available in a compact 20-bump WLP (2mm x 2.5mm).

· Operating temperature range: -40°C to +105°C.

FEATURES

· High configurability: Supports programmable driver configuration, current limit (100mA or 200mA), and linear regulator voltage (3.3V or 5V).

· Integrated functions: Programmable comparator, PWM oscillator, digital potentiometer, and LED driver for visual feedback.

· Robust protection: Reverse polarity, short circuit, thermal shutdown, ±6kV ESD protection, and ±1kV/500Ω surge protection.

· Small form factor: Ultra-small 20-bump WLP (2mm x 2.5mm).

· Wide operating voltage: 4.75V/8V to 36V.

APPLICATIONS

· Industrial binary sensors.

· Proximity switches.

· Inductive and magnetic sensors.
