The TPS3808G01MDBVTEP is a comprehensive power management supervisor chip used to monitor a variety of system parameters and take the necessary corrective action when a fault or other unexpected condition occurs. It is an ultra-low-power and cost-effective power management supervisor integrated circuit (IC) especially suited for portable devices, embedded systems, and other systems that require reliable power management.

The TPS3808G01MDBVTEP is a member of Texas Instruments’ TPS38 family of supervisors, designed for use in a variety of embedded applications with space, power, and other considerations. The TPS3808G01MDBVTEP is equipped with a variety of protection and monitoring features, including over-voltage, under-voltage, over-temperature, open load, and leakage detection. The device is also capable of providing a variety of reset outputs, including active-low and active-high device reset outputs and open drain output forsystem reset.

The TPS3808G01MDBVTEP is offered in a compact 8-pin package, consuming only 0.1µA of quiescent current and providing a wide operating range of 1.2V to 3.6V. The device offers an integrated power-on reset (POR) timer, which can be programmed by two external capacitors to wait up to 1.3s after power-on before releasing the reset.

For applications requiring higher accuracy or wide-ranged monitoring, the TPS3808G01MDBVTEP also provides an adjustable independent reset (IRQ) comparator. The device’s output can be configured to multiple pins, allowing fine-grained control of external circuitry.

The TPS3808G01MDBVTEP is the ideal choice for protecting the integrity of your application, providing reliable system monitoring and support for the most demanding embedded systems. The device provides an integrated over-temperature-protection feature for thermal conditions that exceed the programmed maximum trip point. In addition, the device offers an adjustable independent reset comparator for accurate trip point and reset assertion.

In addition to over-voltage and under-voltage protection, the TPS3808G01MDBVTEP provides simple open-load and leakage detection to further protect against power-related events. Its two integrated power-good outputs indicate general system power availability and can be configured with one- or two-cycle reset delay.

Typical applications for this device are system reset and monitoring, real-time clock and battery backup, system power control and status, and power supply control and protection. Its combination of low power, wide operating range, and integrated features make it an ideal choice for designers looking to protect their designs and ensure reliable system operation.
