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.
