Hosiden Using Dialog’s USB Power Delivery Chipset

20 March 2018

Dialog Semiconductor plc has started shipping its USB Power Delivery (USB PD) chipset to Hosiden Corp., a Japanese manufacturer of charger adapters for smartphones.

The chipset will be used in Hosiden’s CBC2153 model USB PD-compliant adapter that works with mobile TELCO providers. Hosiden says it is using the USB PD chipset because it requires fewer external components compared to traditional microcontroller-based approaches and with a high efficiency it can support the high power and fast charging demands of the USB PD specification at a low cost and in a small form factor.

The chipset eliminates the need for an MCU and additional external components that result in a higher power density in a small charger case. Features include Dialog’s SmartDefender advanced hiccup technology to address soft short circuits, prevent excessive heat build-up and damage in charger cables and connectors. An automatic AC unplug detection protects the phone battery from high voltage if the charger is unplugged, then re-plugged in to the mains with the charging cable still connected.
