TL7757ILPE3

TL7757ILPE3 is an advanced power management IC (PMIC) that combines including a positive voltage supervisor and programmable reset IC. It is used in a variety of applications, such as industrial equipment and automotive systems. It is designed to provide a reliable voltage monitoring with flexibility, precision, and stability.

Application Field

TL7757ILPE3 makes a variety of applications requires power monitoring and protection. It is used in Industrial equipment and automotive systems, such as temperatures sensors, automotive ECM (engine control module) systems. It provides single power supplies such as microprocessor systems and supply voltage regulation.

Working Principle

TL7757ILPE3 is a positive voltage supervisor with a reset output. It monitors a positive input voltage and provides an output when the input voltage breaks certain thresholds. The reset output is triggered low when the input voltage falls below the preset threshold voltage. The device also has a delay feature to prevent premature reset at startup. Once the input voltage is stabilized, the reset output is released. The threshold voltage and the delay time of reset output can be programmed with external capacitors. It is capable of monitoring a wide input voltage range from 2.07 V to 5.50 V.

The device also has power-on reset (POR) and power-down reset (PDR) features according to the input voltage. In addition, the POR and PDR functions are locked out to prevent glitches during power-up and power-down conditions. Furthermore, the device provides active-low enable and reset outputs for power supply sequencing. The reverse supply current of the device is lower than 1 uA, protecting precious battery power.

TL7757ILPE3 provides extended temperature range of -40ºC to +125ºC, reduces component count and board space. This is ideal for design engineer who seeks small form factor, low power consumption, and high performance supervisor.

Conclusion

In conclusion, TL7757ILPE3 is an advanced PMIC, featured with positive voltage supervisor, programmable reset, a wide input voltage range, and extended temperature range. It is widely used in industrial equipment, temperatures sensors, and automotive systems, providing reliable power monitoring and protection. This supervisors supports active-low enable and reset outputs for power supply sequencing, reducing component count and board space.
