Motion SPM® Device Portfolio
Note: The 'XX' in the part numbers (FNA4XX) indicates current rating (Ic at Tc = 25 C); e.g. FNA41560B2: Ic = 15A.
SPM2
Targets high power applications up to 75A/600V. Sense-IGBT’s on low-side for over-current protection and a built- in thermistor for temperature monitoring. 15A – 30A modules in ceramic substrate packaging. 50A and 75A modules in Direct Bond Copper (DBC) substrate packaging to reduce thermal impedance. Input gate signals are active low.
- FSAMxxSM: SM indicates mid switching frequency and low conduction loss.
- FSAMxx SH: SH indicates high switching frequency and low switching loss.
SPM3
Targets a wide range of power applications from 3A to 30A/600V. Input gate signals are active high.
SPM3 V2 requires external pin connections between Vs and U/V/W output respectively.
- FSBSxxCHxx: S indicates ceramic substrate packaging for the 3A, 5A, 10A, 15A, and 25A modules.
- FSBBxxCHxx: B indicates Direct Bond Copper (DBC) substrate packaging for the 15A, 20A, and 30A modules.
SMP3 V4 has an internal connection for Vs, built-in bootstrap diodes and over-temperature protection.

| BLDC Ripple Torque Reduction via Modified Sinusoidal PWM (2008-2009) A brushless direct current (BLDC) fan motor driver system using sinusoidal PWM (SPWM) is introduced. The driver board is assembled in the motor to minimize the system size. Based on the signal from the hall position sensor on the board, the controller generates the SPWM input for the power module to drive the BLDC motor. Because it is a sinusoidal PWM instead of a square PWM, both vibration and noise are lower. Experimental results are presented to verify the stability of the driver system. |   |
