The LM2726M/NOPB is a high-performance gate driver PMIC integrated circuit that is designed to amplify the gate-drive power of a low voltage gate control switch. This IC is particularly suitable for driving power field-effect transistors (FETs) and insulated gate bipolar transistors (IGBTs) in applications like motor control, switching power supplies and Class D audio amplifier circuits. The main benefit of using the LM2726M/NOPB is the high peak current capability, which ensures a clean switching action and improved efficiency. The LM2726M/NOPB also supports a wide range of operational voltages, making it suitable for a variety of applications.

The LM2726M/NOPB is designed as a three-stage charge pump voltage doubler that is capable of converting a 5V logic level signal into a voltage-controlled gate drive. The first stage is a high-side charge pump that is activated by the Enable (EN) input. When enabled, the devices\' internal capacitors are charged to the VDD voltage level and reversed-biased feedback diodes isolate the outputs from the low-side rail. The second stage is a voltage-controlled gate driver circuit, which takes its input from the EN+ and EN- terminals. The EN+ and EN- ports are connected to a voltage-controlled amplifier, which is used to translate the logic level signal into a variable gate drive voltage. The third stage is a low-side charge pump that is used to reduce the gate drive voltage to the required level.

The LM2726M/NOPB also integrates several safety features. It includes an over-current and over-temperature protection circuit, as well as a thermal shutdown circuit. The over-current protection feature prevents the FETs from being damaged by excessive heat generated during abnormal operation. The thermal shutdown circuit limits the maximum temperature of the FETs in order to protect them from being damaged.

The LM2726M/NOPB is suitable for high-power applications like motor control, switching power supplies and Class D audio amplifier circuits. It is designed to be scalable and data-controllable, allowing users to easily integrate their own circuitry onto the IC. The device is housed in a 14-pin PowerSSO package and it is rated for operation from 4.5V to 15V. The device supports a number of operational features, such as adjustable dead-time control and a flip-flop latch, which allows the gate signal to remain at the same level regardless of the input signal.

In summary, the LM2726M/NOPB is a high-performance gate driver PMIC integrated circuit that is specifically designed to amplify the gate-drive power of a low voltage gate control switch. The device is capable of supporting a wide range of operational voltages, which makes it suitable for a variety of applications. It is housed in a 14-pin PowerSSO package and it is rated for operation from 4.5V to 15V.
