DA4100 is a highly integrated System-on-Chip WattUp RF-transmitter IC designed to provide optimal charging of WattUp receiver devices. It forms the core of the Near Field WattUp transmitter system and is designed to charge a range of devices fitted with WattUp receivers. It features the RF transmitter, power management and integrated DC-DC supply, delivering a complete WattUp transmitter system solution.  Applications include the wireless charging of low-power, battery-powered devices, such as wearables, fitness trackers, hearables, hearing aids, Bluetooth® trackers, smart pens and other devices.

Features:

  • DA4100 integrates most of the functions required to form a complete WattUp transmitter system including an ARM Cortex® M0+ processor, RAM, ROM, crystal oscillator, Low Profile Oscillator (LPO), clock divider, Phase-Lock Loop (PLL), RF converter, Variable Gain Amplifier (VGA), Power Detectors (PD), DC-DC, LDO’s, I2C, UART, SPI, GPIOs, ADCs and DACs.
  • Embedded secure element for 2-way authentication with 128bit encryption.
  • The device only requires an external crystal and power amplifier and operates directly from a 3.3V power supply.

Benefits

  • RF/antenna-based solution
  • Smaller antenna than coil-based designs
  • Improved spatial and orientation freedom
  • Eliminates connectors and charging contacts
  • Enables fully sealed waterproof design
  • Enables distance charging
