L99H01XP

Overview

The L99H01XP is a motor bridge driver designed for automotive applications, manufactured by STMicroelectronics. It controls four external N-channel MOS transistors in a bridge configuration for DC-motor driving. The device features an integrated standard Serial Peripheral Interface (SPI) for output control and diagnostics, along with a free configurable current sense amplifier. It operates within an operating supply voltage range of 6 V to 28 V and supports PWM operation up to 30 kHz. The component utilizes a central two-stage charge pump and includes interface pins for external MOSFET thermal sensors.

Feature Summary

• Integrated SPI interface for comprehensive output control and diagnostic information reporting
• Configurable current sense amplifier with zero adjust capability for end-of-line trimming
• Central two-stage charge pump enabling full RDSon performance down to 6 V for normal level MOSFETs
• Dedicated interface pin for connecting thermal sensors from external MOSFETs

Applications

• DC-motor driving in automotive applications
• Motor bridge driver configurations
• Automotive motion control systems

Procurement Notes

Verify the current lifecycle status before procurement, as the L99H01 series may be marked as Not Recommended for New Designs (NRND). Confirm package availability and lead times directly with authorized distributors or the manufacturer. Ensure compatibility with existing design specifications regarding the SSOP-36 package and automotive qualification requirements prior to ordering.

Selection Notes

Select this component for designs requiring precise control of four external N-channel MOSFETs in a bridge topology. The integrated SPI interface simplifies system connectivity compared to parallel control schemes. Consider the 6 V to 28 V operating range and the specific requirement for external MOSFETs when evaluating power management needs. Verify that the 30 kHz PWM frequency meets the application's dynamic response requirements.

Part Context

The L99H01XP belongs to STMicroelectronics' family of motor drivers specifically engineered for automotive environments. It serves as a bridge driver solution, distinct from pre-drivers or single H-bridge controllers. The 'XP' suffix indicates the PowerSSO-36 package variant. This part integrates high-side and low-side drive capabilities through external components, focusing on robustness and diagnostic feedback for vehicle systems.

Replacement Considerations

Check for updated revisions within the L99H01 family. Consult official substitution lists for equivalent bridge drivers if the NRND status impacts long-term supply. Verify pinout and electrical parameter compatibility before transitioning to alternative parts.
