Additional Details

The MAX14832 is a 24V, 100mA driver for industrial binary sensors. The device is configurable through one-time programming (OTP) and integrates the common high-voltage circuitry needed for industrial binary sensors into a single-device solution. Integrated transient protection meets IEC60255-5 surges up to ±1.3kV.

The output of the device can be configured for high-side (pnp), low-side (npn), or push-pull operation through OTP. Additionally, the device features an OTP option for the internal low-dropout (LDO) regulator, allowing the user to select a 3.3V or 5V output, as well as an option to configure the device for sensors with normally open (NO) or normally closed (NC) logic. Also configurable during OTP is the timing of the power-on reset (POR) delay. OTP programming options are performed with the sensor interface pins (V_CC, DO, and GND) using the 1-Wire^® interface protocol.

The MAX14832 operates from a wide 4.75V to 34V supply and is available in a 10-pin TDFN-EP (3mm x 3mm) package and 9-bump wafer-level package (WLP) (1.6mm x 2.0mm). The device functions over the extended -40°C to +85°C temperature range.
