TL7702ACD

TL7702ACD is a supervisor circuit from Texas Instruments, categorized as PMIC (Power Management Integrated Circuit). It is designed as a push-pull method reset logic circuit with wide range of operating voltage, and works with all type of low power circuits, microprocessors and all embedded systems. The TL7702ACD provides an adjustable reset threshold, fault sensing with two on-chip N-Channel open-drain outputs and programmable watch-dog timer and manual reset input.

TL7702ACD is a highly integrated, low power supervisor circuit and it is widely used in embedded systems, automotive and medical applications. The product is available in an easy to use, miniature 16-Pin Thin Shrink SOIC (TSSOP) package.

The TL7702ACD has an adjustable voltage supervisor and a dedicated reset oscillator. The reset voltage is adjustable by setting the resistor R1 for the desired low voltage trip point. The reset time can be configured to the required value. The TL7702ACD also has an integrated window watchdog timer. This timer can be configured both for an active low level and active high level reset output. The reset output can be used to reset micro-controllers, DSPs, FPGAs and other embedded systems.

The TL7702ACD has advanced protection circuitry that prevents output plunger voltage exceeding the allowed ratings. This feature is essential in automotive and medical applications, as they are subjected to extreme environmental conditions. The open drain outputs also give improved immunity to EMI/RFI and transient over-voltage shocks.

The operational characteristics of the TL7702ACD make it ideal for use in embedded systems. Its high current source and sink capabilities (up to 2mA) allows it to drive multiple loads without sacrificing performance. The precision at which the reset trip threshold is adjustable also allows for precise voltage monitoring and thus more reliable circuit operation. The low quiescent supply current makes it suitable for battery-powered applications.

In summary, the TL7702ACD is an excellent choice for supervisors in embedded systems, automotive, and medical applications. It is capable of driving multiple loads with minimal power loss while providing high-precision accuracy, excellent protection against electrical overstress, and programmable watchdog timer.
