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.
Feature
• Selectable PTCO output current IPTCO = 1 μA (TCTH01xxE, Typ.) IPTCO = 10 μA (TCTH02xxE, Typ.) • High PTCO output current accuracy ±8 % (VDD = 3.3 V, 25 °C) • Low current consumption IDD= 1.8 μA (TCTH01xxE, Typ.) IDD= 11.3 μA (TCTH02xxE, Typ.) • FLAG signal latch function (TCTH0x2xE) • FLAG signal output (PTCGOOD) TCTH0xxAE: Push-pull type TCTH0xxBE: Open-drain type • Standard package ESV (SOT-553) (1.6 mm x 1.6 mm x 0.55 mm) “ThermoflaggerTM” is a trademark of Toshiba Electronic Devices & Storage Corporation.
