The MAX30031–MAX30034 are patent-pending protection devices intended to (with the help of external, energy-rated resistors) absorb repetitive defibrillation and other high-energy pulses to protect sensitive electronic circuitry in ECG and other medical/industrial equipment. The devices can withstand over 100,000 defibrillation pulses without failure.
The devices are intended to replace the gas-discharge tubes and transient absorbers in applications where its significant reduction in size is beneficial and its lower, well defined on-voltage can offer higher degrees of protection to sensitive electronics.
The devices use a combination of a rugged integrated circuit process and high-speed circuitry to ensure very fast turn-on times with trigger voltages low enough to not require secondary clamping circuitry. A low hold current of approximately 175mA ensures protection is maintained for the entire length of the high-energy transient event.
The MAX30031–MAX30034 are available in a small, 3mm x 5mm µMAX-8 package and are specified over the 0°C to +70°C temperature range.
