High-Voltage (+120V) ASIC for automotive diagnostics
The ASIC contains all major automotive communication protocols like CAN (HS-CAN, SW-CAN), J1850, PWM and OWI. It interfaces with the car ECU (Engine Control Unit) and has a HV (High-Voltage) switch matrix to support multiple car brands. Key Features:
Asynchronous DC-DC controller and driver for automotive Xenon HID lamps
The ASIC generates the required voltages for ignition, startup and normal operation of the lamps. Included are the igniter, H-bridge and the H-bridge driver, which operates the lamp in AC for higher durability. A power regulation loop generates an accurate PWM power control to the lamp up to 35W. The loop stability of the whole […]
128-channel MEMS speaker driver with 1.8V to 90V DC-DC
This ASIC drives a digital MEMS speaker which produces sound by moving 1024 pixels. The High-voltage driver ASIC main goal is to generate the high voltage supply levels and to drive the individual rows and columns of the MEMS device. The ASIC is co-packaged together with the 8mmx8mm MEMS element and protected by a coating […]
Electrode arrays for nerve stimulation in cochlear implants
ICsense has implemented direct nerve stimulation electrode arrays and nerve response telemetry for cochlear implants. The key challenge was to deliver an accurate charge to the tissue and be able to measure identical charges from the tissue. As the electronics are wirelessly powered, low power consumption is crucial. The response of the nerves and brain […]
40-channel DBS brain stimulation and recording ASIC
The ASIC is part of a novel DBS system with at least 40 electrodes for steering brain stimulation and brain recording. The ASIC is close to the electrodes, not part of the IPG/INS. For safety, AC power is transferred to the ASIC through a dedicated DC-AC-DC conversion scheme over the lead cable together with the […]
High-memory passive EPC Gen 2 RFID tags
In cooperation with Tego Inc. and Easics, a high-memory EPC RFID Class-1 Generation-2 UHF RFID compliant passive RFID tag is developed. This tag was selected by Airbus to perform maintenance management on their newest airplanes. The extended non-volatile memory of 32kbytes exceeds standard commercial tags (512 bits) and the interface capabilities are unrivalled. Moreover, the memory […]
