TA6009FN/FNG
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA6009FN,TA6009FNG
Shock Sensor IC (1 ch version)
TA6009FN/FNG detects an existence of external shock through
the shock sensor and output.
Features
•
•
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.
Differential input impedance = 100 MΩ (typ.)
•
•
•
LPF (low pass filter) circuitry is incorporated.
Cut-off frequency of LPF = 7 kHz
Sensitivity of shock detection can be adjusted by external devices.

Figure 1 The Composition of G-Force Sense Amplifier
Figure 1 is the composition of G-Force sense amplifier.
The shock sensor is connected between 1 and 2 terminal.
When G-force Sensor (sensor sensibility
=
s (mV/G)) is used to detect external shock of g (G), the external
parts are determined as following.
