TPS3808G25DBVR

Integrated circuit (IC) supervisors are devices used to protect the processor\'s power system by triggering the reset function if a malfunction or instability is detected in the system. One of the main integrated circuit (IC) supervisors is the Texas Instruments (TI) TPS3808G25DBVR.

The TPS3808G25DBVR is an advanced supervisor IC that provides an extremely low power supervisor for KeyStone II and C64x+ control processors. This device features an adjustable reset window, an integrated power on reset, an input supply voltage detector (ISVD), and factory-trimmed low-voltage detection with guaranteed accuracy.

The TPS3808G25DBVR can be used in applications with a wide range of supply voltages. The VT pin can be used to monitor the supply voltage and provide a reset signal when the supply voltage drops below the preset threshold. The TPS3808G25DBVR is factory-trimmed to guarantee accuracy in the low supply voltage margin detection.

The TPS3808G25DBVR can perform a reset of the processor when the output logic is set to a logic low voltage. The reset is triggered when the supply voltage drops below the preset threshold voltage or when a manual reset is applied. The reset is then delayed by the reset timer to avoid too many reset pulses. In order to ensure a proper reset, the reset pin of the device is driven high to indicate that the processor is being reset.

The TPS3808G25DBVR has a wide variety of applications. It can be used in data communications systems, industrial control systems, consumer electronic products, medical systems and high-performance CPUs. It is also used for automotive applications such as engine control systems, safety systems, immobilizers, body electronics and entertainment systems.

The working principle of the TPS3808G25DBVR is quite simple. The device monitors the supply voltage with the VT pin. When the voltage drops below the preset voltage or when a manual reset is applied, the reset pin is driven low and the processor is reset. After a preset time delay, the reset pin is driven high to indicate a successful reset of the processor.

In summary, the TI TPS3808G25DBVR is an integrated circuit (IC) supervisor that can provide an extremely low-power supervisor for KeyStone II and C64x+ control processors. This device features an adjustable reset window, an integrated power on reset, an input supply voltage detector (ISVD), and factory-trimmed low-voltage detection with guaranteed accuracy. It is used in a wide range of applications and its working principle is simple.
