LS6526(2013) Datasheet PDF - LSI Computer Systems

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 Li battery as a source of energy for its operation. The detailed description of the functional blocks is as follows (refer to Figure 2).

FEATURES:
• Power derived from 3.0V Lithium battery
• VDD operating range 2.3V to 3.6V
• 25μA maximum quiescent current (LS6525)
• 30μA maximum quiescent current (LS6526)
• Direct interface with PIR sensor
• Analog signal and digital interrupt signal outputs for interfacing
   with a MCU
• 2.175V regulated output
• Low battery indicator output (LS6526)
• LS6525 (DIP), LS6525-S (SOIC)
   LS6526 (DIP), LS6526-S (SOIC)

APPLICATIONS:
   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.
