產品總覽

The MAX4822ETP+ is a 3.3V/5V, 8-channel relay driver with fast recovery time and power save mode in 20 pin TQFN package. It offers built-in kickback protection and drives 3.3V/5V nonlatching or dual coil latching relays. A zener kickback protection circuit significantly reduces recovery time in applications where switching speed is critical. The MAX4822 has unique power save mode where the relay current can be reduced to level just above the relay hold current threshold after activation. Input data is shifted into a shift register and latched to outputs when complementary CS transitions from low to high. Built-in hysteresis (schmitt trigger) on all digital inputs allows this device to be used with slow rising and falling signals such as those from optocouplers or RC power-up initialization circuits. The MAX4822 is used in ATE equipment, DSL redundancy protection (ADSL/VDSL/HDSL), T1/E1 and T3/E3 redundancy protection and test equipments (oscilloscopes, spectrum analyzers).
  • Supply voltage range from 2.3V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Coil drive current of 70mA
  • Maximum on-resistance of 5ohm at VCC = 2.7V, IOUT
  • = 70mA
  • Active-low SET/active-low RESET functions to turn on/off all outputs simultaneously
  • Serial digital output for daisy chaining
  • Low quiescent supply current of 180µA (VCC = 5.5V) and dynamic supply current of 1.6mA (VCC = 5.5V)
  • 10MHz SPI/QSPI/MICROWIRE compatible serial interface
  • Zener clamping voltage of 9V, turn-on time of 1µs and turn-off time of 3µs
  • Power save mode keeps the relay activated while significantly reducing power consumption
