TA6009FM
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA6009FM
Shock Sensor IC (1 ch version)
TA6009FM detects an existence of external shock through the
shock sensor and output.
Features
·
·
TA6009FM 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.
TA6009FM 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.
Small package
SON10-P-0303-0.50 (0.5 mm pitch)
Weight: 0.016 g (typ.)

The configuration of G-force sensor 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.
