Description
This TI Design implements a universal power supply with programmable output voltage and innovative smart e-Fuse technology for use in a multi-standard position encoder interface module on an industrial drive. The eFuse provides inrush-current and over-current protection as well as user programmable over and under-voltage protection with limits accurate across the industrial temperature range. This design is realized to meet EMC immunity requirements for ESD, Fast Transient Burst and Surge according to IEC61800-3.
Features
- Power supply design supports different supply voltage requirements for a wide range of position encoders with digital or analog interface
- Offers a wide input voltage range, 18-36 V (24-V nominal) and high efficiency (>80%)
- Output voltage programmable from 5-V to 15-V with <15 mVpp ripple at 300mA load current
- Output protection with innovative eFuse technology, inrush-current limitation, and protection against overcurrent, over- and under-voltage. Protection limits are constant across the industrial temperature range
- Fault handling: Disconnect in case of fault, enable pin for power supply reset. Fault and
- Power Good indicator flags for diagnostics
- Designed to meet EMC requirements for ESD, EFT, Surge according to IEC61800-3.
