Introduction

Dialog’s battery management solutions are optimized to meet the challenging needs of today’s smartphones. Tight space constraints, thermal challenges and ever changing power requirements are effectively addressed through Dialog’s portfolio of highly integrated, highly efficient and easily configurable PMICs.

Dialog also offers innovative, highly efficient and high-density charging solutions that reduce heat dissipation for any rapid charging technology.

Battery Management

Highly integrated solutions offer space saving and cost-effective smartphone solutions
The integration of multiple switching regulators and LDOs meets the diverse power management needs of advanced SOCs and conserves valuable board space. Additionally, these highly integrated solutions deliver higher reliability, reduced complexity and provide layout flexibility.

Flexible and configurable for multiple SOC platforms
Dialog’s comprehensive solutions meet the challenges of powering today’s advanced application processor and modem SOCs with diverse voltage and current needs, multiple channels, power sequencing requirements and the ability to scale to higher power needs.

PMIC and sub-PMIC families meet wide-ranging needs in today’s applications
In addition to highly integrated PMIC solutions with integrated multiple buck regulators and LDOs, Dialog offers a family of high-current sub-PMICs that satisfy the high-current needs of the latest SOCs. These sub-PMICs offer multi-phase, high-current (up to 20 A) buck regulators in a compact footprint with advanced power management features.

Charging ICs

Dialog offers a high-efficiency companion charger solution for rapid charging delivering up to 2.5 A charging current, and direct charging solutions that can deliver up to 6 A charging current to the battery using a standard 3 Amp USB cable. Dialog’s highly efficient inductor-less switched capacitor DC/DC converter enables 1S mobile devices to migrate to 2S battery configuration without any changes in the regulated voltage rails.

The DA9318 is a high-voltage inductor-less current doubler powering up to 44 W, with integrated protection features and incredible power efficiency of up to 98%, and has an input voltage range of 5.5 V to 10.5 V.

The DA9155M is a 2.5 A companion charger with 92% peak efficiency for 1S battery applications, and has an input voltage range of 4.3 V to 13.5 V for all rapid charging technologies.

Switched Capacitor Converters 

Dialog Semiconductor is first in the industry to launch DA9313, an ultra-efficient Buck Converter that does not require the use of inductors. This differentiated technology is leading the way in optimizing next-generation mobile devices.

This family of devices - also referred to as Switched Cap Dividers - can offer up to 98% efficiency at high power levels. The combination of “almost loss-less” conversion and high power density make it ideally suited to power the emerging design trends in Smartphones. Major benefits of this unique technology include direct charging of single cell Lithium Ion batteries - enabling usage of standard 3A low-cost USB cables to deliver up to 6A of charging current, 75% reduced routing losses and more than 50% reduction in PCB board area – all within a package height of less than 1mm.

The DA9313 – Dialog’s 1st-Gen offering - can provide up to 10A of current in a 10mm2 offering with an extremely flat efficiency curve at a peak efficiency of 98.2% over a wide range of output current loads. It can also operate in a Master-Slave configuration to deliver up to 20A. The DA9313 also offers enable and power-good functions and can be configured to operate in a fixed-frequency mode.

AC/DC Rapid Charge™ adapter solutions

As the leader in AC/DC RapidCharge solutions, Dialog supports more fast-charging protocols than any other supplier, including USB Power Delivery 3.0 (USB PD 3.0); Qualcomm® Quick Charge™ 4+, 3.0 and 2.0 technologies; Samsung Adaptive Fast Charging (AFC); direct charge; and other proprietary OEM protocols.

Haptics

Haptics technology recreates the sense of touch to the user by applying forces and vibrations in the form of touch feedback in displays, touch surfaces and buttons. The DA728x family of High-Definition (HD) Haptic Drivers, combine custom drive sequences, on- and off resonance, at up to 1kHz. The device can drive both ERM and LRA (narrow and wideband) actuators and track resonance up to 300Hz to drive the most complex click/vibration touch effects in a wide range of applications.

As haptic drivers spend the majority of their time in standby/idle mode, the DA728x family was designed to utilize very low idle current consumption (360nA) to maximize battery life.

The DA728x family combines very low idle current consumption with low-latency trigger inputs to minimize system power consumption. Integrated trigger inputs allow haptic operation without waking the application processor, and latency times at sub-1ms give real switch behavior - 10x better than any other solution available today.
