STSPIN840 Description
The STSPIN840 is a compact brushed DC motor driver able to drive two bi-directional brushed DC motors simultaneously. It integrates, in a very small 4 x 4 mm QFN package, both the control logic and a fully protected low RDSon dual full-bridge power stage. Thanks to a dedicated PARALLEL input pin the parallel mode function can be enabled, transforming the device into an equivalent and more powerful single full-bridge able to deliver up to 3Arms current at an equivalent HS + LS RDSon of 500 mΩ.
The STSPIN840 embeds two independent PWM current controllers (one for each full bridge) based on user-settable values of the reference voltage and OFF time.
