TOSHIBA BiCMOS Linear Integrated Circuit Silicon Monolithic
TB6066FNG
Shock Sensor IC
TB6066FNG detects an existence of external shock through the
shock sensor and output Low-level signal at 7 pin.
It has so excellent characteristic in S/N ratio that user can use
Analog signal for mechanical control systems, like servo control.
Features
TB6066FNG 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.
Input terminal of sensor signal is designed high impedance.
Differential input impedance = 100 M (typ.)
Three Operatinal-Amplifier is built in for design flexibility. (*Note 1)
Sensitivity of shock detection can be adjusted by external devices.
Small package: SSOP16-P-225-0.65B (0.65 mm pitch)
Excellent S/N ratio: Improved 10dB compared with our TA6038FN/FNG
*Note 1: LPF (low pass filter) circuitry is not bulit in. User needs to make some filter with one
operational-amplifier to cancel the signal of resonant frequency of piezo sensor

TOSHIBA is continually working to improve the quality and reliability of its products. Nevertheless, semiconductor
devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical
stress. It is the responsibility of the buyer, when utilizing TOSHIBA products, to comply with the standards of
safety in making a safe design for the entire system, and to avoid situations in which a malfunction or failure of
such TOSHIBA products could cause loss of human life, bodily injury or damage to property.
