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 in 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 reference voltage and OFF time.
The devices can be forced in a low consumption state reducing the total current consumption down to less than 45 μA.
As with all other devices from the STSPIN family, the STSPIN840 integrates a complete set of protections for the power stages (non-dissipative overcurrent, thermal shutdown, short-circuit and undervoltage lockout) making it a bulletproof solution for the new wave of demanding industrial applications.
