DESCRIPTION (See Figure 5)

The LS6511N, LS6512 and LS6513 are CMOS integrated circuits designed for detecting motion from a PIR Sensor and initiating appropriate responses.

FEATURES:

• Direct Interface with PIR Sensor

• Two-Stage Differential Amplifier

• Amplifier Gain and Bandwidth externally controlled

• True and Complementary Output Drives

• Separate digital filters for processing positive and negative input signals

• Single Pulse/Dual Pulse/ Concurrent Pulse Detection

• Adjustable Output Pulse Width

• Optional 5V Shunt Regulator Output

• 75µA Typical Supply Current

• Undervoltage Detection

• LS6511N(DIP); LS6511N-S (SOIC) - See Figure 1A

LS6512(DIP); LS6512-S (SOIC) - See Figure 1A

LS6513(DIP); LS6513-S (SOIC) - See Figure 1B

APPLICATIONS:
