TENS-NS4 Highly Integrated Transcutaneous Electrical Nerve Stimulator(TENS) DATASHEET
●The battery charger enables an external Li-OH battery to be connected directly to the chip with all charging phases managed internally. All digital and analog supplies are regulated internally with built-in regulator from the output of the supply switcher.
●A built-in boost converter (DC-DC) enables the generation stimulator voltages up to 55V simply from the battery supply. An internal control block regulates the operation of the voltage booster.
●The stimulator block is designed to drive anodic and cathodic stimulation currents pulses up to 57mA. The elevated supply voltage from the boost converter provides additional compliance headroom to the stimulator thus allowing a wide range of stimulator loads.
●An embedded touch sensor functionality allows the processing of capacitive touch inputs as an alternative to physical button inputs.
●The NS4 generates multiple stimulation patterns to support various end applications. In the conventional TENS mode 4 sub-stimulation patterns are available. A second Electrical Muscle Stimulation mode is available with individual Athlete Strengthening and Muscle Rehabilitation patterns.
■Features:
●Operating Voltage Range: 3.5V to 5V
●Operating Temperature Range: 0 to 85C
●Operation Frequency: 1MHz
●Operation power: from battery or USB or wireless charger
●Integrated Battery Charger
●Integrated Touch Sensor inputs
●Self-starting internal oscillator
●Integrated High Voltage Boost Converter with Overvoltage Limiter
