BTS640S2GATMA1 Integrated Circuits (ICs)

BTS640S2GATMA1 is a power distribution switch, load driver, or power management integrated circuit (PMIC). As a control switch, it is commonly used in switching power applications such as computers, communications equipment, and audio-video systems. The BTS640S2GATMA1 is a low-side load driver that utilizes a level shift technique that ensures the switch is always closed when a voltage below ground is present. This ensures the device does not affect the normal operation of the system being powered. The BTS640S2GATMA1 is capable of switching up to 0.5A of current and has an operating voltage range from 0V to 18V.The BTS640S2GATMA1 has two input pins, an enable pin and a control pin. The enable pin is used to turn the device on, it must be pulled high to an active level in order to enable the device. The control pin enables the user to control the output off or on based on the logic level applied here. A logic 0 level turns the device off, while a logic 1 level turns it on.The BTS640S2GATMA1 also has two output pins, an open drain and a low side driver output. The open drain output provides a supplemental RC filter to reduce inductive and capacitive interference, while the low side driver output provides a direct control of the output device. Both outputs are connected to the same capacitor, so when the output is enabled, both capacitors discharge at the same rate, which is beneficial for controlling application where a sudden voltage drop must be prevented.The BTS640S2GATMA1 is available in a variety of package sizes and has an operating temperature range from -40°C to +125°C. This device is capable of both single as well as parallel operation and has built-in protection against current overload and short circuit. The BTS640S2GATMA1 has an ESD protection of 2000V, making it useful for outdoor applications where exposure to electrostatic fields is common.In summary, the BTS640S2GATMA1 is a low-side load driver PMIC that is suitable for switching power applications. It features an enable and control input pin, and two output pins for both open drain and low side driver outputs. The BTS640S2GATMA1 is available in a variety of package sizes and has an operating temperature of -40°C to +125°C. Its built-in protections make it an ideal choice for applications that may be exposed to electrostatic fields.
