MC34912G5ACR2

Power Management - Specialized Overview

The MC34912G5ACR2 is a System Basis Chip (SBC) designed for Local Interconnect Network (LIN) applications. It integrates a LIN transceiver with predrivers and a low dropout regulator. The device operates within a supply voltage range of 5.5V to 18V and supports an operating temperature range of -40°C to 85°C. It features a 5.0V LDO capable of delivering 50mA or 60mA output current. The component is housed in a 32-LQFP package measuring 7x7 mm. Supply current is specified at 4.5mA. The part status is listed as obsolete.

Power Management - Specialized Feature Summary

• Integrates LIN transceiver with full SPI readable diagnostics
• Includes 5.0V low dropout regulator with protection and reporting features
• Provides LIN 2.5G predrivers for actuator control

Power Management - Specialized Applications

• Automotive body electronics systems
• LIN-based sensor and actuator networks
• Vehicle comfort modules requiring integrated power management

Power Management - Specialized Procurement Notes

Verify availability carefully as the MC34912G5ACR2 is classified as obsolete by NXP USA Inc. Sourcing may require checking secondary distributors or evaluating replacement components. Confirm package integrity and RoHS compliance upon receipt. Ensure design-in compatibility with existing PCB layouts before procurement due to end-of-life status.

Power Management - Specialized Selection Notes

Select this component only if legacy support for the specific 32-LQFP form factor and integrated LIN/SBC functionality is required. Consider the obsolete status when planning long-term production cycles. Evaluate alternative active parts from the same family if future supply stability is a priority. Verify that the 5.0V LDO current capability meets system load requirements.

Power Management - Specialized Part Context

This part belongs to the MC3491x series of System Basis Chips from NXP Semiconductors. These devices combine interface and power management functions into a single solution for automotive LIN networks. The G5AC suffix typically denotes specific packaging and temperature grade variations within the product line, distinct from other variants like the MC34911 or MC34932 series.

Power Management - Specialized Replacement Considerations

Check for active equivalents such as the MC34912G5ACD or newer revisions within the MC3491x family. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
