L9698-TR - Automotive Ignition IGBT Driver | STMicroelectronics
MPN: L9698-TR ✓ NakahandaL9698-TR Ulas
An ignition IGBT driver is a specialized power management IC that controls the current through an ignition coil to generate the high-voltage spark required for combustion in gasoline engines. It sits between the engine control unit (ECU) and the ignition coil, converting low-power logic signals into high-current pulses. In the system hierarchy, it belongs to the category of power management ICs, specifically within automotive power drivers and ignition control modules.
Key features of the L9698-TR include a collector-emitter voltage rating of 400V, a collector current capability of 10A, and a low saturation voltage of 1.5V at 5A, ensuring efficient power transfer. The device integrates a Darlington configuration with a built-in collector-emitter clamp diode, protecting against inductive load transients. It also features an internal current sense output for diagnostic purposes, enabling real-time monitoring of ignition coil current.
The L9698-TR utilizes a bipolar Darlington architecture, which provides high current gain and simplifies the drive circuitry. The integrated clamp diode absorbs the energy stored in the ignition coil during the off-state, preventing voltage spikes that could damage the driver. The device operates over a junction temperature range of -40°C to +150°C, making it suitable for harsh automotive environments. Its PowerSO-10 package with exposed pad ensures efficient heat dissipation, critical for high-current operation.
Typical applications include direct ignition systems, distributorless ignition systems (DIS), and coil-on-plug (COP) configurations. The L9698-TR is also used in motorcycle and small engine ignition systems, as well as industrial ignition for gas turbines. Its high-voltage capability and robust protection make it ideal for demanding ignition applications.
When designing with the L9698-TR, ensure adequate PCB copper area for thermal management, as the device can dissipate significant power during ignition pulses. The input control signal should be properly conditioned to avoid false triggering, and the current sense output should be filtered to prevent noise interference. Proper layout of the high-current path is essential to minimize parasitic inductance.

Talaan ng Disenyo
The L9698-TR can dissipate up to 2.5W during ignition pulses. Ensure adequate PCB copper area and thermal vias to the exposed pad to keep the junction temperature within limits. A minimum of 1 square inch of copper is recommended for continuous operation at high duty cycles.
Place the input capacitor (0.1uF) close to the IN pin and the current sense resistor close to the SENSE pin to minimize noise. The high-current collector and emitter traces should be short and wide to reduce parasitic inductance and resistance.
Do not exceed the maximum collector-emitter voltage of 400V. Ensure the input signal is clean and free of glitches to prevent false triggering. The current sense output should be filtered with a small capacitor to avoid noise interference.
