Overview
The L99H02QFTR is a half-bridge MOSFET gate driver designed for automotive DC motor control applications. It operates within an input voltage range of 6 V to 28 V and features two drivers with two outputs. The device delivers an output current of 38 mA, with rise and fall times of 170 ns and 210 ns respectively. It supports PWM operation up to 30 kHz via an SPI interface and includes a central two-stage charge pump. The component is AEC-Q100 qualified and functions between -40°C and +150°C.
Feature Summary
- Integrated central two-stage charge pump enabling 100% duty cycle operation
- Configurable current sense amplifier with zero adjust for end-of-line trimming
- Embedded thermal sensing circuitry for external MOSFET monitoring
- Programmable power management including free-wheeling control
Applications
- Automotive brushed DC motor control
- Body and convenience systems
- Door actuator drivers
Procurement Notes
Verify the specific suffix QFTR indicates the reel packaging format when ordering. Confirm that the target application requires the 38 mA output drive capability and the LQFP-32 package dimensions. Ensure the system design accounts for the specified operating temperature range and AEC-Q100 qualification requirements for automotive deployment.
Selection Notes
Select this component for designs requiring a robust half-bridge driver with integrated diagnostics and SPI control. It is suitable for applications needing high-side driving capabilities down to 6 V supply voltages. Consider the 38 mA output current limit and the specific thermal management needs associated with the LQFP-32 package for the final implementation.
Part Context
This part belongs to STMicroelectronics' VIPower family of automotive motor drivers. It is specifically engineered to drive external N-channel MOSFETs in an H-bridge configuration. The device integrates protection features and diagnostic interfaces required for modern automotive body electronics and motor control systems.
Replacement Considerations
The EVAL-L99H02XP evaluation board is designed for the L99H02XP variant. Verify pinout and functional compatibility if substituting with other L99H02 series members such as L99H02QF.
