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 M (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. Small package SSOP10-P-0.65A (0.65 mm pitch) Weight: 0.04 g (typ.)

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. (gain setting) * 10 PIN GND 500/(s x g) = G1 G1/10 = G (OP-AMP) (HPF setting) fc = 1/(2 x R1 x C1) (LPF setting) fc = 1/(2 x R2 x C2)
