MAX22520GWP+

MAX22520GWP+ is a one-time programmable (OTP) industrial sensor output driver. It is a line driver for industrial sensors that incorporates a one-time programmable (OTP) analog interface for signal conditioning of binary switching sensors. Sensor calibration and configuration settings can be permanently programmed with the inline data interface using one-time programming (OTP). Additionally, an accurate integrated linear regulator provides a programmable (3.3V or 5V) low-noise supply for analog signal-sensing circuitry. The driver output (DO) is configurable using the Maxim® 1-Wire® protocol and an OTP interface to permanently operate in a normally-open or normally-closed state and in a high-side (PNP), low-side (NPN), or push-pull configuration. The maximum driver load current can be programmed to 100mA (min) or 200mA (min). It is used in applications such as industrial binary sensors, proximity switches, and inductive and magnetic sensors.
