MAX30034 Defibrillation/Surge/ESD Protector General Description Benefits and Features The MAX30034 is a patent-pending protection device Low Leakage Defibrilliation Protection IC Helps ECG intended to (with the help of external, energy-rated resistors) Systems absorb repetitive defibrillation and other high-energy Low Capacitance ~ 3pF pulses to protect sensitive electronic circuitry in ECG Low Leakage ~ 20pA at +70C and other medical/industrial equipment. The device can Fast Turn-On < 2ns withstand over 100,000 defib pulses without failure. Low On-Voltage 3.9V (typ) The device is intended to replace the gas-discharge tubes High Peak Current in Excess of 4A and transient absorbers in applications where its significant Withstands Over 100k Defibrilliation Pulses reduction in size is beneficial and its lower, well-defined on- Without Failure voltage can offer higher degrees of protection to sensitive 0C to 70C Temperature Range electronics. Small, 3mm x 5mm MAX Package The device uses a combination of a rugged integrated- circuit process and high-speed circuitry to ensure very Applications fast turn-on times with trigger voltages low enough to not AED Units require secondary clamping circuitry. A low hold current Wearable Medical of approximately 175mA ensures protection is maintained Clinical Patient Monitoring for the entire length of the high-energy transient event. Industrial Equipment Protection The MAX30034 is available in a small, 3mm x 5mm Fixed Broadband Wireless Access MAX-8 package, and is specified over the 0C to +70C temperature range.
