The HK7022A-1 is a SOT-89-3 surface-mount, RoHS-compliant microprocessor and microcontroller supervisor manufactured by HK. It is designed to provide accurate reset timing for microprocessors and microcontrollers. It features a push button reset circuit, programmable time-out period, adjustable reset delay and a wide reset voltage range of 1.4V – 5V. It includes an adjustable reset threshhold, an open-collector reset output, and a reset output active low. The SOT-89-3 package also allows excellent thermal and electrical performance with low power consumption and minimal board space.
