LTC1629EG-6#PBF

PMIC - Voltage Regulators - DC DC Switching Controllers

The LTC1629EG-6#PBF is a high voltage P-Channel MOSFET gate driver from Linear Technology Corporation that enables low voltage logic to control high voltage loads. It is designed for high efficiency switching applications where low power dissipation is key. The device works by generating a MOSFET gate drive signal using a low voltage logic input. This allows the device to be used in applications such as motor control, LED lighting, and battery charging.

The device works by using a low voltage logic input to generate a high voltage MOSFET gate drive signal. The input voltage can range from 0 to 80 volts. The output gate drive has a gate-to-source voltage drop of 0.6V and can control MOSFETs with gate-source capacitances up to 600pF. The output can also be connected with a 10kΩ pull-up resistor to enable fast switching and improved noise immunity.

The device also features undervoltage lockout protection that monitors the input voltage supplied. When the input voltage drops below a certain threshold, the device will latch off the output until the input voltage is restored. It also features internal thermal protection that will shut off the output if the temperature inside the device exceeds a certain threshold. The device also features overcurrent protection which will shut off the output if the current exceeds a certain threshold. The device has a maximum operating frequency of 200kHz and can handle up to 6A of current.

The device is the perfect choice for high efficiency switching applications that require a low power dissipation and a high voltage MOSFET gate drive signal. It is well suited for applications such as motor control, LED lighting, and battery charging. The device is available in a 6-pin SOT-23 package with extended temperature range from -40C to 125C.
