• Manufacturer Part Number: ta6009fn
• Description: Shock Sensor Ic 1 Ch Version
• Manufacturer: TOSHIBA Semiconductor CORPORATION

Application Note
sensor
Shock
parts are determined as following.
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
