L99H02XPTR

Overview

The L99H02XPTR is a motor bridge driver designed for automotive applications, specifically intended to drive four external N-channel MOS transistors configured in an H-bridge topology. It integrates a freely configurable current detection amplifier and features a standard Serial Peripheral Interface (SPI) for device control and diagnostic information retrieval. The component includes an interface pin for external MOSFET thermal sensors and supports PWM operation with frequencies up to 30 kHz. It operates within a supply voltage range of 6 V to 28 V and is qualified under the AEC-Q100 standard.

Feature Summary

• Integrates a central two-stage charge pump capable of driving external reverse battery NMOS protection.
• Includes a freely configurable current detection amplifier with zero-point calibration for line-end regulation.
• Features programmable freewheeling power management and detection circuits for external MOSFETs with embedded thermal sensors.

Applications

• Automotive DC motor drive systems
• H-bridge configuration for external N-channel MOSFETs

Procurement Notes

Verify that the specific suffix 'PTR' corresponds to the required tape-and-reel packaging format as defined by STMicroelectronics. Confirm that the component meets the AEC-Q100 qualification requirements necessary for your specific automotive application environment. Ensure that the SPI interface compatibility aligns with your system's microcontroller or controller architecture before finalizing procurement.

Selection Notes

Select this component when designing automotive motor control systems requiring an integrated bridge driver solution. It is suitable for applications needing precise current monitoring via the internal amplifier and robust diagnostic capabilities through the SPI interface. Consider the 6 V to 28 V operating range and the integration of thermal sensor interfaces when evaluating system-level power and safety requirements.
