Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify product status as the STK681-200-E is listed as obsolete or no longer manufactured by onsemi. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing system designs before procurement due to end-of-life status. Check for RoHS compliance details and specific packaging requirements such as bulk quantities if applicable.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for applications requiring a dedicated hybrid driver for brushed DC motors with PWM current control. Consider the 4.2 A output capability and 12-SIP package form factor for space-constrained designs. Evaluate thermal management needs given the operating temperature range up to +105°C. Verify interface logic levels match the control system requirements.

Full Half-Bridge (H Bridge) Drivers Part Context

The STK681-200-E belongs to the STK681 series of hybrid motor drivers from onsemi. This series includes variants like the STK681-320 and STK681-360-E, which share similar functional architectures but differ in output current ratings and package pin counts. The STK681-200-E specifically offers a 4.2 A output in a 12-pin SIP format, distinguishing it from higher-current counterparts.
