| Linear four digital power manager has when powerful GUI development process can be accelerated |
| MILPITAS, CA (Linear Technology Corporation) has recently published EEPROM power supply manager LTC2974, used for comprehensive management for digitization have four or more power supply terminal of the power supply system. LTC2974 uses I2C PMBus interface and command set to monitor and control the positive or negative power, when the power system design, development, production and failure analysis, can provide rapid troubleshooting and debug capabilities. Any one have a "run" pin power available through the track based sequencer, and control or time.
LTC2974 can simultaneously monitor four channels of voltage and current, and external temperature, allowing users to compensate for the shift MOSFET RDS (ON) or inductor DCR. Each power supply can be used throughout the digital servo loop over the temperature range of adjustment and trimming margin, which can measure the voltage supply terminal and continuously adjusted to maintain accuracy. The LTC2974 can supply all functions without compromising the accuracy of conditional execution, with better than ± 0.25% total unadjusted error.Users can take advantage of the powerful LTpowerPlay ™ GUI to configure and intuitive look LTC2974 registers, user settings and fault records. The need for four-powered applications, LTC2974 is available 1-wire synchronous bus be connected in series so that the shared components on the same bus error handling to achieve commonality error handling.
LTC2974 suitable for a wide variety of applications, including uninterruptible power system (UPS), automotive, medical, video, and Internet applications. LTC2974 built-key build modules, such as differential measurement and adjustment, high-resolution data converters, high retention EEPROM and a precision reference to achieve digitization in pure analog power management system. A watchdog timer can be set to provide for an external microcontroller, FPGA, ASIC monitoring. All four channels are fully functional, with proprietary monitoring, supervision, sequencing, margining, trimming, fault protection.Black Box provides a method for recording a fault in the fault diagnosis of faults through time to save the key parameters in the EEPROM. When the external field, LTC2974 can operate autonomously in order to provide continuous monitoring and to take measures to cope with pre-set failure. LTC2974 also has an internal temperature sensor to protect the grain, this high level of mixed-signal integration ensures LTC2974 can be easily and reliably manage the most complex power supply system.
Jia Ruling Technology’s LTC2974 8-channel devices LTC2978, as the company continues to expand Digital Power Management product line, one member, and complements Linear complete stand-alone DC / DC regulator product line, such as 15A LTM4627 or dual 8A LTM4628, which uses 15mm x 15mm in μModμle ® package.
LTC2974 is available in a 64-pin 9mm x 9mm QFN package, RoHS-compliant components and characteristics suitable for commercial and industrial temperature ranges. | | |  |
