Philips RDT: Improving Patients’ Outcomes Throughout the Continuum of Care

Remote Diagnostics Technologies (RDT), a Philips business unit located in Hampshire, U.K., develops innovative remote monitoring and resuscitation solutions for pre-hospital and critical care services. The company got its start in 1997, with the aim of addressing challenges around monitoring patients in remote locations and securely transmitting medical data in real time to trusted support or care organizations. Today, RDT’s team of more than 100 specialist engineers, designers, developers, and more are internationally recognized for their state-of-the-art medical monitoring solutions. The company became part of the Royal Philips family in June 2018.

Challenges

  • Sought small, low-current RTC with I2C compatibility

Solutions

Benefits

  • Small footprint
  • Low-power operation
  • Shorter design cycle

Philips RDT’s Tempus Pro is one of the market’s smallest, lightest, and most rugged pre-hospital vital sign monitors available. The feature-rich device provides advanced patient data collection and sharing, real-time data streaming, easy in-field expansion options, and smart mount solutions.

Challenges

Philips RDT’s Electronics team manages the electronics hardware design and development of the company’s vital signs medical monitoring equipment and accessories. Its portfolio of comprehensive, connected emergency care solutions complements Philips’ Advanced Life Support solutions and strengthens its leadership position in the resuscitation and emergency care market. Moreover, the addition of RDT significantly empowers Philips to innovate, drive digital transformation in healthcare, and enter new markets.

For its Tempus Pro monitor, Philips RDT sought a real-time clock (RTC) IC with a calendar. Given the requirements of its portable device, it was important that the IC have a small footprint, the required temperature and voltage supply ranges, I2C compatibility, and low current consumption, noted Neil Lundy, technical manager of Electronics at Philips RDT.

Solutions and Benefits

After evaluating a number of products, Lundy and his team selected Maxim’s DS1340 I2C RTC with trickle charger and software clock calibration. According to Lundy, the DS1340 met the team’s technical criteria and, compared to other available devices, “was more suitable for medical products.” Available in an 8-pin µSOP or SO package, the DS1340 manages all timekeeping functions with low timekeeping voltage down to 1.3V. “The DS1340 gave us a shorter design cycle as it has a built-in crystal,” Lundy noted.
