Programmable Battery Charger IPs For SoC Applications

May. 29, 2017, May. 29, 2017 – Since its inception in 2008, Chipus has been developing a series of analog power management IPs, including linear regulators, power-on resets, ultra low power references (voltage and current), and power management units, using various architectures, and employed by customers worldwide in various application areas.

Chipus is now building out its power management offerings by expanding its line of battery charger IPs, designed for modern mobile and IoT applications, where battery powered solutions are ubiquitous.

In 2013, Chipus has launched its first linear Li-Ion battery charger IP (CM1711ff) for SilTerra 0.18um CMOS technology. Last year, the second generation (CM1712ff) designed for SilTerra 0.18um BCD technology was announced and a third generation (CM1713ff) is already under development, with release planned for the second half of 2017.

Chipus familiy of battery charger IPs consist of a completely integrated, precision Li-ion battery charger IP block (4.2V+-1%) suitable for portable applications. They are capable of charging from AC adapters or USB source and can include an internal NTC, among several other important and useful features for SoC integration.

Chipus has built a wealth of best practices for Li-ion battery management, which differentiates their battery chargers and enables advanced capabilities. This includes integrated protection against overheating of the die and of the battery, over/under voltage, and reverse current protection.

As an example, with autonomously adaptive charging modes and easily reconfigurable maximum charge current, Chipus battery charger IPs provide suitable current profiles for different Li-ion batteries guaranteeing their full performance and life span.

Main features

• Programmable charge current: 10mA to 1.5A
• Easy integration in SoC
• Integrated power FET
• Trickle, fast, and constant voltage charging modes
• Integrated protections (voltage, temperature, reverse current)
• Charging status flags
• Easy porting to other technologies
