Full Half-Bridge (H Bridge) Drivers Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted or unavailable through major authorized channels such as Mouser Electronics. Verification of current stock status from alternative suppliers is required before procurement planning. Due to the discontinued status, lead times and supply continuity cannot be guaranteed by the original manufacturer.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Engineers selecting this part must account for its End-of-Life status when designing new products. The specific electrical ratings, including the 450 V supply limit and 20 kHz switching frequency, define its operational envelope. The SIP package format requires appropriate PCB layout considerations for thermal management and pin alignment. Compatibility with existing motor control architectures should be validated against the single-ended output configuration.
