The TPS3807A30DCKT is a supervisory integrated circuit (IC) that monitors system activities and provides reset control. It is a parametrically-specified reset supervisor circuit specifically designed to prevent system memory loss, hang ups, and other system errors which sometimes overrun a real-time operating system (RTOS).

The circuit can also be used to awaken a system from power-down or sleep mode when reset sequences are initiated or a voltage threshold is crossed. In addition, the circuit helps protect against short-circuiting and blackouts by resetting the system back to its original and proper state.

This integrated circuit provides system reliability in applications such as smartphones, tablets, laptops and portable devices. It is also suitable for many industrial and automotive applications. In addition, a low external component count, high supply voltage range, and low dropout voltage make the TPS3807A30DCKT easy to use for portable electronic devices.

The TPS3807A30DCKT family is a reset solution that is specifically designed for low-power applications, high capacitance and high poWer sequencing applications. The device is available in a small 4-pin SOT-23-5 package and has an operating temperature range from -40°C to 85°C.

The TPS3807A30DCKT supervisor is a high performance, low power and delay time reset IC. With an accuracy of -3.5%/-3.7V, it can detect VDD down to 0.58V. The reset signal is asserted by an active high reset pin (RST) when VDD reaches a predetermined threshold voltage (VTRIP). This signal is used to control the reset of the system.

The supervisor provides three different options to post-reset the system, such as a manual reset, active high reset input, or a power-on reset. The manual reset allows manual reset of the supervisor by setting RST to ‘low’, while the active high reset input allows the reset signal to be reset by an external signal. The power-on reset mode allows the system to be reset when the power is turned on.

The core of the supervisor circuit is the basic voltage-monitored (VM) reset scheme. In this scheme, a comparator circuit is used to monitor the supply voltage and reset the system when the voltage reaches a predetermined threshold level (VTRIP). The comparator is connected to an external voltage-level-selectable resistor that controls the voltage threshold.

When VDD is below the trip-voltage level, comparator output is asserted and RST is held low (reset). When VDD is above the trip-voltage level, the RST is deasserted and the system is released from reset. Once the trip-voltage level is reached, the reset signal is released, allowing the system to resume operation. The reset signal is released separately for each reset type.

The TPS3807A30DCKT is designed with protection circuitry to ensure that the circuit does not consume large amounts of energy. This protection can be enabled or disabled through the use of an external pin or by setting a bit in the internal configuration register. When it is enabled, the device intermittently monitors the supply voltage in standby mode, reducing overall power consumption.

In addition, the TPS3807A30DCKT provides a wide supply voltage range, up to 6.5V. It also features an advanced power-on-reset (POR) functionality with an adjustable time-delay (up to 20ms). The adjustable delay helps prevent potential power glitches in order to ensure a smooth power-on reset.

The TPS3807A30DCKT reset supervisor is an ideal solution for many portable electronic devices and other system applications. Its low-power operation and reliable performance offer a dependable system protection. In addition, the wide supply voltage range and adjustable delay time make it suitable for a broad range of applications.
