The SN75372DR is an integrated, high-performance, low-power drain line driver, made from silicon gate CMOS technology and is part of the line of logic circuits from Texas Instruments. This device is categorized as an integrated gate driver for PMIC (Power Management ICs), offering a low power supply voltage feature, ranging from 4.75V to 5.25V, as well as an extra 5V tolerant enable pin. It is mainly used to drive MOSFETs, IGBTs, logic level, or standard gate outputs of other logic PCBs featuring NMOS or PMOS outputs.

The SN75372DR is characterized by having its FLG (Free Logic Gate) output control feature at a 0.8V lower than that of the normal low voltage operation of 4.75V. This feature greatly reduces power supply voltage requirements. The device also features a True Output pin, which helps designers to identify the state of the output regardless of the signal connected to it. This ensures that the logic level of the output is maintained over time.

Additionally, the SN75372DR contains two built-in blocking diodes, internally connected between its output pins and its power supplies, which limits the voltage range that can be applied to the output pins for protecting the gate driver output from voltage transients. The device has an open-drain output pin, allowing it to be used with a wide range of devices.

Working with the SN75372DR is also very easy due to the single-anode to single-Cathode diode array, featuring a user-configurable active-low or active-high protocol. The device is enabled with a single logic signal giving the user the flexibility to control the state of the output using either its input logic pin or the control logic pin. Additionally, the enable logic feature on this device allows the user to control whether the output signal is active or inactive.

In terms of performance, the SN75372DR gate driver offers an impressive pin-to-pin capacitance of 1pF, as well as 0.4A Peak/Continuous Gate current, 10ns Propagation Delay, and a maximum on-state voltage of 7V. The device also has an operating temperature range of 40°C to 85°C, the widest in the PMIC gate driver product family.

Overall, the SN75372DR is a great choice for applications needing high speed switching and low power supply voltage requirements such as portable devices, mobile phones, medical implants, and a variety of automation tasks. The wide voltage range and low gate capacitance of the device make it an ideal solution for gate driver applications requiring high efficiency and accuracy.
