The TL7770-12CDW from Texas Instruments is an integrated circuit system supervisor designed for reset control in microcomputer and microprocessor power-supply systems. This device features two independent supply-voltage supervisors that monitor for overvoltage and undervoltage conditions.
Key electrical characteristics include a wide supply-voltage range of 3.5 V to 18 V. The reset output becomes active when VCC exceeds 1 V during power-up. A time-delay function activates as VCC approaches 3.5 V, latching the reset outputs for a specified duration after system voltages normalize. The device offers precision overvoltage and undervoltage sensing.
For overvoltage conditions, an internal silicon-controlled rectifier (SCR) can be triggered, providing up to 250 mA peak output current for driving external SCR gates. The TL7770-12CDW provides true and complementary reset outputs and allows for externally adjustable output pulse duration.
This supervisor IC is housed in a 16-SOIC package and is designed for surface mount applications. The operating temperature range is 0°C to 70°C.

The TL7770-12CDW operates with a supply voltage from 3.5 V to 18 V.
It monitors two supply voltages.
Reset activation occurs as the supply voltage approaches 3.5 V; reset is defined when VCC exceeds 1 V.
The typical reset output pulse duration is 270 ns, determined by an external timing capacitor.
The TL7770-12CDW is available in a surface-mount 16-SOIC package (0.295 inch, 7.50 mm width).
The operating temperature range is 0°C to 70°C.
It provides a maximum 250 mA peak output current for driving SCR gates.
