典型应用电路以及 MAX14827 评估板主要特性 ,电路图 ,材料清单和 PCB 设计图 .  
The MAX14827 integrates the high-voltage functions commonly found in industrial  
sensors, including drivers and regulators. The MAX14827 features two ultra lowpower  
drivers with active reverse-polarity protection. Operation is specified for normal 24V  
supply voltages up to 60V. Transient protection is simplified due to high voltage tolerance  
allowing the use of micro TVS.  
The device features a flexible control interface. Pin-control logic inputs allow for operation  
with switching sensors that do not use a microcontroller. For sensors that use a  
microcontroller, an SPI interface is available with extensive diagnostics. For IO-Link  
operation, a three-wire UART interface is provided, allowing interfacing to the  
microcontroller UART. Finally, a multiplexed UART/SPI option allows using one serial  
microcontroller interface for shared SPI and UART interfaces.  
The device includes on-board 3.3V and 5V linear regulators for low-noise analog/logic  
supply rails.  
The MAX14827 is available in a (4mm  
4×mm) 24-pin TQFN package and a (2.5mm ×  
2.5mm) 25-pin wafer-level package (WLP) and is specified over the extended -40  
to  
+125 temperature range.  
MAX14827 主要特性 :  
High Configurability and Integration Reduce SKUs  
IO-Link Compliant Transceiver  
Auxiliary 24V Digital Output and Input  
2.3 Ω (typ) Driver On -Resistance  
Selectable Driver Current: 50mA to 250mA  
SPI or Pin-Control Interface for Configuration and Monitoring  
Multiplexed SPI/UART Interface Option
