Nerve Stimulation
Highly Integrated Programmable Stimulus Chip
The NNC6121 is a highly integrated programmable stimulation SOC chip with an ARM microcontroller, a configurable boost DC converter, and a multi-channel highly flexible stimulation driver circuit. The NNC6121 can also provide a single-channel stimulation current output of up to 67mA, and the stimulation waveform can be programmed arbitrarily, which can be flexibly applied to a variety of extracorporeal electrical stimulation devices.
Highly integrated
Integrated ARM microcontroller, configurable boost DC converter and multi-channel highly flexible stimulation driver circuit, this design significantly reduces the size of the device, reducing production costs.
Programmable
Through the dedicated programming interface, users can flexibly configure and adjust the operating parameters of the chip, such as stimulation waveform, frequency, pulse width, amplitude, etc., according to specific treatment needs.
Multiple Boost Circuit Options
Two types of boosting circuits are available for users to choose from, i.e., built-in MOS boosting circuit and external MOS boosting circuit.
Constant Current Source Technology
Able to control the stimulation current more stably, the current waveform can be kept relatively stable after entering the human body, avoiding the change of current waveform and damage to the surrounding tissues in the human body that may be caused by the traditional constant voltage source technology.
