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).  
ESV  
Weight: 2.98 mg (Typ.)  
Application (Ex)  
Notebook PC, Mobile equipment, home appliance, Industry equipment  
etc. for over temperature detection.
