Overview
The LB1947VC-XE is a PWM current control type bidirectional DC motor driver IC manufactured by Sanyo. It operates within a voltage range of 10V to 45V and utilizes a fixed OFF time for current regulation. The component is housed in a 15-pin HZIP (SIP) package designed for through-hole mounting, facilitating integration into motor control circuits requiring precise speed and direction management.
Feature Summary
- PWM current control with fixed OFF time architecture
- Bidirectional drive capability for DC motors
- Through-hole SIP-15P packaging for robust mounting
Applications
- DC motor speed control systems
- Bidirectional motor positioning applications
- Industrial automation motor drivers
Procurement Notes
Verify the manufacturer origin, as sourcing data references both Sanyo and ON Semiconductor/AMI Semiconductor due to corporate acquisitions. Confirm the specific suffix 'XE' matches the required pinout and thermal characteristics. Ensure the package is genuine HZIP-15 and not a generic equivalent. Request original datasheets to validate electrical parameters against the 10V-45V operating range before finalizing procurement.
Selection Notes
Select this component when a dedicated bipolar parallel motor driver with integrated PWM current control is required. The fixed OFF time feature simplifies external circuit design compared to variable timing alternatives. Consider the 15-pin SIP form factor for compatibility with existing through-hole PCB layouts. Verify that the 45V maximum voltage rating aligns with the system's power supply constraints.
Part Context
The LB1947 series belongs to Sanyo's lineup of PMIC motor drivers. The VC-XE variant specifically denotes the HZIP-15 package configuration. This family targets applications needing reliable bidirectional control without complex external logic. The transition of Sanyo's semiconductor assets to ON Semiconductor may affect part numbering conventions and documentation availability.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing requires verifying pin compatibility and electrical ratings against alternative bipolar motor drivers from ON Semiconductor or other manufacturers.
