The BD48L26G-TL is a Type 2, low voltage supervisors circuit. It is an integrated circuit, or IC, that combines several functions into a single package and is part of a Power Management IC (PMIC). The BD48L26G-TL is used in a wide variety of applications, including overvoltage and undervoltage protection, power supply sequencing, power boot and fault detection, and reset generation and management. The BD48L26G-TL also provides a variety of other functions, such as temperature and humidity sensing, analog-to-digital conversion, and system control.

The BD48L26G-TL can be used in a variety of applications, from mobile devices to automotive applications. It is designed for harsh environments, such as high temperatures, high humidity, and vibration. It can be used in applications such as automotive powertrain, railroad, and automotive in-wheel hub motors. It is also suitable for use in medical, communications, computer peripherals, and consumer entertainment products.

The BD48L26G-TL is a low-voltage supervisor that monitors the power supply input voltage and generates a reset signal when the supply voltage is outside the specified range. The reset signal is used to immediately shut down the external circuitry. The reset signal can also be used to toggle the output voltage, allowing the external circuitry to switch to an alternate power source when the supply voltage is too low. The reset signal is also connected to a latch circuit that prevents the circuit from being reset if the supply voltage stays within the specified range. This feature prevents unnecessary shut down of the external circuitry.

The BD48L26G-TL also has an integrated over-voltage protection (OVP) circuit. When the supply voltage rises above the OVP threshold, the OVP circuit triggers an alarm or shuts down the system, ensuring that the device does not suffer from power surge or overvoltage. The OVP circuit also monitors the power supply input voltage and generates a reset signal when the voltage falls outside the specified range. This reset signal is used to immediately shut down the external circuitry.

The BD48L26G-TL also has a watchdog timer. This timer monitors the system and triggers a reset signal if it does not receive a system clock signal within a specified time interval. The reset signal is used to reset the system and prevent any unintentional device operations. The watchdog timer is powered by an internal oscillator and is used to detect system malfunctions.

The BD48L26G-TL also has an analog-to-digital conversion (ADC) module. This module converts the input voltage into digital form, allowing the device to measure a wide range of input voltages, from 0 to 72 V. The ADC module also allows the device to monitor temperature and humidity and provide temperature and humidity data to the controller. The ADC module also performs other tasks, such as voltage and current monitoring, voltage and current regulation, and system control.

Finally, the BD48L26G-TL provides a number of configurable parameters, such as reset threshold, reset output type, and watchdog timer period. These parameters allow designers to customize the device to their particular application, ensuring that the device meets their specific requirements. The device also includes short circuit protection, ensuring the safety of the system.

The BD48L26G-TL is an excellent choice for applications that require reliable and tolerant overvoltage, undervoltage, and overcurrent protection. It is also suited for applications that require accurate system control and secure reset capability. With its wide range of advanced features and configurable parameters, the BD48L26G-TL is an ideal solution for a variety of low-voltage supervisor applications.
