What are the key features of L9958TR?
- SPI-controlled H-bridge with 2.8 A continuous and 5 A peak output current for brushed DC motor drive
- On-chip diagnostics reporting overcurrent, thermal shutdown, and under-voltage lockout via SPI status register
- PWM frequency up to 20 kHz with integrated current limiter and selectable slew-rate control in 20-pin PowerSOIC
What is L9958TR used for?
The L9958TR is designed for automotive body-control modules, power-window actuators, and seat-position motors where SPI configurability and robust diagnostics are essential. It also finds use in industrial conveyor drives and HVAC damper actuators that require precise PWM speed control of brushed DC motors up to 2.8 A. The extended -40°C to +150°C operating range makes it a reliable choice in under-hood and dashboard environments exposed to extreme temperatures.

Frequently Asked Questions
What is the continuous output current rating of the L9958TR and how does it handle peak loads?
The L9958TR delivers a continuous output current of 2.8 A and can sustain peak currents of up to 5 A for short durations, making it suitable for stall conditions in automotive window-lift and seat-adjustment motors without requiring an external current-sense resistor thanks to built-in current limiting.
How does SPI control benefit automotive designers using the L9958TR in body-control modules?
Via its SPI interface, designers can configure current-limit thresholds, slew rate, and PWM duty cycle from a host MCU while simultaneously reading back 8-bit fault status covering overcurrent, thermal shutdown above 175°C, and under-voltage lockout below 4.5 V, reducing external component count in space-constrained body-control PCBs.
What PWM frequency range does the L9958TR support for motor speed control?
The L9958TR supports PWM input frequencies up to 20 kHz, enabling smooth and audibly quiet motor speed control while minimizing switching losses. This range covers both slow-decay and fast-decay recirculation modes, giving engineers flexibility to tune efficiency and EMI characteristics for their specific brushed DC motor load.
Is the L9958TR a suitable drop-in upgrade from a discrete H-bridge for a compact automotive PCB?
Yes. Integrating the full H-bridge, gate drivers, 2.8 A current limiter, and SPI diagnostics into a single 20-pin PowerSOIC footprint of approximately 12.8 mm × 7.5 mm, the L9958TR replaces four discrete MOSFETs plus a gate-drive IC, cutting BOM count significantly and shrinking PCB area in automotive applications rated to 150°C.
