Description
The LS6525 / LS6526 is a CMOS integrated circuit designed for detecting motion from a PIR sensor and is microcontroller interface ready. It uses a 3.0V Lithium battery as a source of energy for its operation. The detailed description of the functional blocks can be found on the datasheet. The low operating voltage and low current drain make the LS6525 / LS6526 ideal for microcontroller-based portable applications such as battery operated motion detectors and photographic equipment, automatic doors, intrusion detection, and anywhere electric outlets are not available.
Features:
• Power derived from 3.0 Volt Lithium Battery
• Vdd Operating Range 2.3V to 3.6V
• 25 uA / 35uA maximum quiescent current ( LS6525 / LS6526)
• Direct Interface with PIR Sensor
• Analog signal and Digital Interrupt signal outputs for interfacing with an MCU
• Regulated 2.175V output
• Low Battery Indicator (LS6526)
