L9904

Overview

The L9904 is a motor bridge controller designed for automotive applications featuring an ISO 9141 bus interface. It operates with a supply voltage range of 8V to 28V, supporting a maximum overvoltage of 40V. The device includes a step-up converter allowing operation at 6V and utilizes a charge pump for driving power MOSFETs as reverse battery protection. It supports PWM operation frequencies up to 30kHz and offers programmable cross-conduction protection time. Quiescent current in standby mode is less than 50μA. Integrated protections include overvoltage, undervoltage, short circuit, and thermal safeguards.

Feature Summary

ISO 9141 compatible interface for automotive control communication
Integrated charge pump enables reverse battery protection via power MOSFET driving
Comprehensive diagnostic capabilities with real-time status monitoring
Programmable cross-conduction protection to ensure safe switching operations

Applications

Automotive motor bridge control systems
ISO 9141 bus interface implementations
Reverse battery protection circuits
PWM motor driver control logic

Procurement Notes

Verify the specific ordering suffix to confirm package type and reel specifications. Ensure compatibility with ISO 9141 protocol requirements for your target application. Check AEC-Q100 qualification status if automotive reliability standards are mandatory. Confirm moisture sensitivity level handling procedures during assembly. Review datasheet for correct pinout configuration relative to your PCB layout design.

Selection Notes

Select this component when an ISO 9141 interface is required for motor control. Consider the 8V-28V operating range and 40V absolute maximum rating. Evaluate the need for integrated reverse battery protection features. Assess if the 30kHz PWM frequency meets your system timing requirements. Verify that the SOIC-20 package fits your spatial constraints.

Part Context

The L9904 belongs to STMicroelectronics' motor bridge controller family. It is categorized under PMIC - Power Management ICs. The device is part of the L9904 series. It is designed specifically for automotive environments requiring robust protection and diagnostic features.
