L9997ND Description

Short technical summary and product information.

The L9997ND from STMicroelectronics is a monolithic integrated dual half bridge driver, built using BCD technology and optimized for automotive applications. This driver is capable of handling an output current of ±1.2A typically, with a maximum DC output current of ±1.8A. It operates within a supply voltage range of 7V to 16.5V, with protection features for supply overvoltage up to 40V.

Key electrical characteristics include a typical RON of 0.7Ω, very low quiescent current in standby mode (<1μA), and CMOS-compatible inputs with hysteresis. The device incorporates essential protection functions such as output short-circuit protection and thermal shutdown, with a thermal shutdown junction temperature of 165°C. Real-time diagnostics for thermal overload and overvoltage are also provided.

The L9997ND is housed in an SO20 package, suitable for surface mounting. Its design is intended for driving various loads, including DC motors, making it a versatile component for automotive electronic systems requiring robust motor control and protection.
