Low Side 0.5A 8ch Digital Output Module for PLC
TIDA-00236: Digital Output Modules are a standard component in a PLC/PAC or DCS to control actuators, motors and other resistive, capacitive or inductive loads. Customers will benefit from this integrated protected low side drivers and the low pin count control interface which saves pins and isolation channels. The design is capable of delivering 0.5A on all 8 channels in a small form factor without compromising thermal management.

LM5072 5V out 25W IEEE 802.3at Compliant POE+ PD Power Reference Design
POE-PD-POWER-REF: This LM5072 based 5V out 25W POE+ PD power supply reference design was prototyped to be fully compliant with IEEE 802.3at standard. The design converts 48 Vdc to 5 Vdc. It can deliver up to 25W power as specified by the IEEE 802.3at standard. It has a 2 event detection circuit which can identify the PSE as either Type one or Type two. ( See National Semiconductor Application note `Fully Compliant IEEE 802.3at Interface Using the LM5072/LM5073` for details ) The 2 event detection circuit is located on the bottom layer of the PC board. In those applications where this 2 event detection feature is not required, the user only needs to populate top layer components. The input current limit is 800 mA. The efficiency of this design is high enough to keep input current under 800mA at 38Vin full load. The input under voltage lock has 7V hysteresis, with 38V rise and 31V fall. This design also has output short circuit protection. This design can also be powered by a 24V AUX power supply. In this configuration, the AUX input port bypasses the LM5072 internal hot swap MOSFET and allows input current to be greater than the 800 mA limit.
TIDA-00896 LDO Regulator Post AC/DC Rectifier Ripple Cleaner Reference Design for Industrial Applications | TI.com
TIDA-00896: The TIDA-00896 reference design provides an easy to implement, low standby current and isolated AC to DC rectification. The AC input voltage is regulated to a ripple free 3.3V using LM2936 a low dropout (LDO) linear regulator. The 3.3V voltage rail is ideal to power microcontrollers which are intended to operate in a low power standby mode most of the time. The low standby quiescent current consumption of LM2936 minimizes the power consumption during the long low power cycles of the system.
