Order now


The LM3881 evaluation board has been designed to connect directly to the power supplies of an existing system to enable sequencing. Upon enabling the device, the three open drain output flags will rise in sequential order, 1-2-3. Once the part is disabled, the shutdown sequence will occur in reverse order, 3-2-1.

  • Power up and power down control
  • Input voltage range of 2.7 V to 5.5 V
  • Small footprint SOT23-6
  • Low quiescent current of 20 mA
  • Capacitor controlled timing options
