Power management integrated circuits, or PMICs, comprise an essential part of any integrated circuit product. PMICs, often referred to as power management chips, are integrated circuits that enable power to be efficiently managed and stored within a system. These devices are crucial to enable safe and reliable operation of the system and facilitate significant reductions in the size and weight of the system. The TLE7809G is a power management chip specifically manufactured by Infineon Technologies and offers certain advantages over other PMICs in the power management area.The TLE7809G is especially suited for applications in connected car domain. It is designed for 12/24V applications and offers several features that make it appropriate for automotive systems. It features an integrated voltage supervisor with a defined reset delay, an adjustable under-voltage reset, a programmable over-voltage lock-out level, and configurable current limit. The device can be used either as a single step or dual step converter with a low Standby current consumption. In addition to automotive applications, the TLE7809G is applicable for a wide range of applications, including power supplies for industrial automation equipment such as factory sensors, DC-DC converters, LED drivers and mobile devices such as phones and computers. The TLE7809G integrates both Pulse Width Modulation (PWM) and Linear Mode regulators into a single chip and operates over a wide temperature range (-40°C to +100°C). The device is also capable of monitoring output voltage to ensure that the voltage is always at its desired level.The TLE7809G device also provides a wide range of safety and protection features, such as current limitation, programmable over-voltage protection, under-voltage lockout, and over-temperature protection. It also features a power-on reset and Brown-Out Reset. The system is also self-protected in case of short-circuits at the output.In terms of its working principle, the TLE7809G is a current-based converter, meaning it has the ability to monitor and adjust the current levels in order to maintain the proper output voltage levels. This is done by comparing the output voltage to a reference voltage and adjusting the current to make up the difference. This allows the TLE7809G make precise voltage adjustments even under harsh load conditions.The TLE7809G is a highly versatile power management device that provides a wide range of features for control and protection of various electronic systems. When compared to other PMICs, the TLE7809G offers the advantage of being capable of operating over a wide temperature range and provide numerous safety features. It is highly suitable for applications in connected car, industrial automation equipment and mobile devices.
