TCTH0xxxE Series
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCTH0xxxE Series
ThermoflaggerTM (Over Temperature Detection IC)
The TCTH0xxxE series are the CMOS process IC outputs abnormal-state signal on
detecting over temperature as the resistor value changing of external PTC
Thermistor.
Output current to PTC thermistor is 1 μA (Typ.) and whole current
consumption is 1.8 μA (Typ.), low consumption operation is realised.
(TCTH01xxE)
Selectable Push-pull type, or Open-drain type for FLAG signal output
by product.
Also, Selectable Auto retry type if PTC thermistor temperature goes down
back to lower than threshold, or Latch the abnormal signal type.
IC package is ESV (1.6 mm x 1.6 mm x 0.55 mm).
