The SM72482MA-4/NOPB is a part of the Texas Instruments SM724xx family of products which arel programmable gate drivers that can be used with a variety of low to medium voltage applications. Specifically, this IC is an advanced gate driver offering high level of integration and flexibility, featuring an integrated N-Channel MOSFET driver, an integrated P-Channel MOSFET driver, and a voltage regulator. The SM72482MA-4/NOPB is intended for use in telecom/datacom and industrial applications, such as pumps, motors, LEDs, fans, and solenoid valves.

The SM72482MA-4/NOPB is a bidirectional gate driver. It features two branches, one for P-channel MOSFETs and one for N-channel MOSFETs. The bidirectional function of the gate driver allows it to be used for both buck and boost modes for DC-DC conversion. Additionally, the SM72482MA-4/NOPB can be used for two-level or pulse-width modulation for AC-DC conversion. This allows the device to be used in consumer, server, and automotive applications.

The SM72482MA-4/NOPB includes an integrated voltage regulator which provides a regulated supply voltage to the gate drivers. The output voltage of the regulator is adjustable between 5.5 V to 12 V with a 0.7V reference. The voltage regulator also includes a low power-on reset (LPOR) function which ensures that the output has reached the steady state before the MOSFETs are enabled. This provides a level of protection against any voltage overshoots or undershoots which may occur during power-up.

The integrated P- and N-channel MOSFET drivers provide a high peak output current which is programmable with an external resistor. The peak output current is designable to a maximum of 5 A for both P- and N-Channel MOSFETs. The MOSFET drive features a floating source operation and the output voltage is adjustable from 0 V to the maximum output voltage.

The SM72482MA-4/NOPB also features protection and fault management features. The device includes current limiting, automatic shutdown, and open circuit protection. Additionally, the SM72482MA-4/NOPB features a programmable watchdog timer with a timeout period of up to 20 ms. This allows the system to identify and rectify any faults which may occur during operation.

The SM72482MA-4/NOPB is an ideal product for use in DC-DC and AC-DC applications due to its high level of flexibility and high level of integration. It is suitable for use in telecom/datacom and industrial applications due to its flexible output voltage and programmable output current. Additionally, the integrated voltage regulator and fault management features ensure reliable and safe operation. This makes the SM72482MA-4/NOPB an ideal choice for a variety of applications.
