Product Details

The MAX14838/MAX14839 24V/100mA drivers are optimized for use in industrial sensors. These devices integrate all of the high-voltage (24V) circuitry commonly found in industrial sensors, including a configurable PNP/ NPN/push-pull driver and an integrated linear regulator that meets common sensor power requirements.

The MAX14838/MAX14839 are pin-configurable. Logic inputs allow the driver to be configured for high-side (PNP), low-side (NPN), or push-pull operation. An additional input allows the user to select between normally-open and normally-closed logic.

The MAX14838 features an onboard 5V linear regulator, while the MAX14839 features a 3.3V linear regulator.

Each device includes two LED drivers for visual feedback. One LED driver reflects the output logic status and the other is a general-purpose driver that can be used to signal a fault condition.

The DO output, supply (VCC), and ground (GND) pins are reverse polarity-protected and are protected against IEC ESD and surge events.

The MAX14838 and MAX14839 operate from a wide supply range and are available in a 12-pin TDFN-EP package (3mm x 3mm) or a 12-bump wafer-level package (WLP) (2.1mm x 1.6mm) and operate over the -40°C to +105°C temperature range.
