Power Management Integrated Circuits (PMICs) are devices capable of controlling and managing the power used by a computer system. A key component of a PMIC’s design is the power distribution switch, which is responsible for distributing the power from the main power source to the system’s components. One of the more popular power switches is the 98-1046C device, which is designed to be an energy efficient solution for numerous applications. In this article, the application field and working principle of the 98-1046C device will be discussed.

The 98-1046C device is designed to be used in many different applications. It’s ideal for applications that demand low voltage supply and energy efficiency such as automotive, industrial, and medical designs. It also has a high level of flexibility; it can be configured to support pulse-width modulation (PWM) or constant current/constant voltage (CC/CV) operation. Furthermore, it can be used as a standalone controller for operating a single load or as a synchronous switch for controlling multiple loads. This versatility makes the 98-1046C device a great choice for a wide range of applications.

The 98-1046C device utilizes a buck-boost architecture, which allows it to be used in systems with input voltages up to 24V. It also has an adjustable current limit that is set by an onboard resistor, making it very easy to configure for any load. The device also has a built-in over-voltage protection feature, which helps to protect against dangerous spikes in the system\'s power. Additionally, the 98-1046C device has an integrated 1.2V regulator with a power-on reset circuit, allowing it to supply 1.2V to the system even during power cycling.

The 98-1046C device uses pulse-width modulation (PWM) to regulate the current, voltage, and temperature of the system’s power by adjusting the on time of the device’s MOSFET transistor. The device has an internal oscillator that runs at a frequency that is set by an external resistor. The PWM cycles are then created based on the frequency of the oscillator and the current limit set. The device also has a power-on reset circuit with an adjustable delay time, allowing the system to startup with a smooth transition.

The 98-1046C device also has a built-in thermalsensor, which helps to protect the device from temperature related issues. The thermalsensor monitors the temperature of the device to ensure that it is operating within its safe temperature range. In addition, the device also uses an enable signal, which can be used to enable or disable the device. This enable signal can also be used to initiate various functions that the device has built-in such as startup and shutdown sequences, over-voltage protection, and power-on reset.

Finally, the 98-1046C device has a wide range of output current range capabilities. This allows it to be used to control and regulate power in applications with different current outputs. The device is capable of providing up to 2 A of total current output, which is sufficient for most loads. Furthermore, it can be used to drive standard loads, low-side switches, and complex gate drivers.

In conclusion, the 98-1046C device is a versatile power switch designed to be energy efficient in a large range of applications. It is ideal for applications that demand low voltage supply and energy efficiency, and its adjustable current limit makes it easy to use with any load. Additionally, it has a built-in over-voltage protection feature and a 1.2V regulator with a power-on reset circuit. Finally, it offers a wide range of output current range capabilities, allowing it to be used with various loads. With all of these features combined, the 98-1046C device is a great choice for numerous applications.
