TA6009FNG

Manufacturer Part Number
TA6009FNG
Description
Shock Sensor IC (1 ch version)
Manufacturer
TOSHIBA [Toshiba Semiconductor]
Datasheet
Shock Sensor IC (1 ch version)
the shock sensor and output.
Features
Block Diagram
TA6009FN/FNG detects an existence of external shock through
TA6009FN/FNG operates from 2.7 to 5.5 V DC single power
supply voltage.
Signal from the shock sensor is amplified according to setting
gain, and is detected through the internal window
comparator.
TA6009FN/FNG incorporates 1-ch shock detecting circuitry.
Input terminal of sensor signal is designed high impedance.
LPF (low pass filter) circuitry is incorporated.
Sensitivity of shock detection can be adjusted by external devices.
Small package
Differential input impedance = 100 MΩ (typ.)
Cut-off frequency of LPF = 7 kHz
