Chipus has been developing battery charger circuits since 2012 and the new IP generation reuses the proven experience of the existing designs with enhanced capabilities.
First generation of battery charger family IP was silicon proven in 2013 in SilTerra 0.18um CMOS and it is capable of dealing with 1.5A charging current in fast charge mode. In order to extend input voltage range, the second generation was designed in BCD technology and it is capable of dealing with up to 30V.
The 3rd generation of battery charger IP (CM1713ff), that is now being fabricated in SilTerra 0.18um BCD (D18V), is designed to consume down to 40 nA in OFF mode (or battery supply mode) and features a programmable output voltage to deal with different battery types. This IP also features a bi-directional power switch, allowing the battery to supply the whole system when the system voltage is lower than the battery voltage. The range of applications now encompasses IoT (Internet of Things) in which the stand-by power consumption is a key parameter.
Technical information about these IPs can be found in this application note.
“It is important to keep the pace in the development of innovative power management IPs. The market is requesting lower power solutions driven by the IoT and mobile trends. Battery lifetime is a strong concern” explains Murilo Pessatti, Chipus’ CEO.
Daniel Mioni, technical leader of the power management team at Chipus, added “we included an aggressive idle mode. Cutting down the power consumption to few nA was a challenge. Programmable fast charge current, battery voltage and end-of-charge current can be configured digitally by writing in a particular register. We are targeting applications that use lithium batteries with different voltages. This new feature gives a lot of flexibility for the user to configure the IP”.
“Concerning the next generation of battery chargers, we have been receiving requests from potential leading customers to develop these IPs in smaller nodes such as 55nm to suit applications that require big digital designs. We already have some interesting and encouraging results at the moment regarding this path”, complements Murilo.
