SPF7302  
Full Bridge DC Motor Driver  
Features and Benefits  
Description  
Supply voltage, VBB, 36 V maximum  
Maximum DC current 3 A continuous, 6 A pulsed (1 kHz,  
duty cycle < 1%, pulse width < 10 μs)  
RDS(on) = 300 mΩ maximum, at TJ = 125ºC  
Operation modes: forward, reverse, brake (high- or low-  
side freewheeling current circulation)  
TheSPF7302isafullyprotected,singlechipfull-bridgedriver  
IC for DC brush motor applications. The various protection  
circuits integrated are: overvoltage protection (OVP);  
overcurrent protection (OCP) with latch, which is adapted  
to the DMOSFETs in each full bridge; undervoltage lockout  
(UVLO); open load detection; and overcurrent limitation.  
Output disable pin (DI pin)  
Protections:  
The package is a thermally enhanced 16-pin HSOP power  
package with an exposed thermal pad on the bottom side of  
the package.  
Overvoltage protection (OVP), 36 V minimum  
Overcurrent protection (OCP), 3 A typical  
Overcurrent limitation (OCL), 6 A typical  
Externally adjustable delay timer to halt OCL  
Thermal shutdown protection (TSD), 151°C minimum  
Undervoltage lockout on VBB (UVLO), 4.2 V minimum  
Open load detection at startup  
Diagnosis output linked to OVP, OCP, TSD, UVLO, and  
open load detection, at startup and in operation  
Package: 16 pin HSOP with exposed thermal pad  
and tabs
