Product details
Overview
TLE9221SXXUMA2 from Infineon Technologies is a high-voltage, high-current automotive-grade half-bridge driver IC designed for controlling inductive loads such as solenoids, valves, and DC motors. It features integrated high-side and low-side MOSFETs, 40 V absolute maximum supply voltage, ±3.5 A continuous output current, and built-in overtemperature and short-circuit protection. Used in engine management and transmission control modules.
For engineers reviewing the TLE9221SXXUMA2 datasheet, TLE9221SXXUMA2 pinout, TLE9221SXXUMA2 application, or TLE9221SXXUMA2 equivalent, key selection criteria include integrated half-bridge topology, diagnostic feedback capability, PWM input compatibility, and AEC-Q100 Grade 1 qualification for under-hood environments.
Technical Context
The TLE9221SXXUMA2 integrates complementary N-channel power MOSFETs with adaptive gate driving and real-time current sensing. It supports 5–28 V supply range, operates up to 150 °C junction temperature, and implements fast current-limit shutdown (< 2 µs) with internal 10-bit ADC for load current monitoring.
Control logic accepts standard TTL/CMOS-compatible PWM inputs and provides configurable fault reporting via dedicated nFAULT pin. Internal charge pump enables high-side MOSFET operation without external bootstrap components, simplifying PCB layout for space-constrained automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5 V to 28 V - Supports full automotive battery range including cold-crank (5 V) and load-dump (28 V) conditions. |
| Continuous Output Current | ±3.5 A - Sustains rated current at 150 °C junction temperature without derating in typical ECU heatsinking. |
| Max Switching Frequency | 25 kHz - Enables precise PWM-controlled actuator positioning without audible noise or thermal stress. |
| Fault Response Time | < 2 µs - Limits energy dissipation during short-circuit events to protect MOSFETs and downstream wiring. |
| Diagnostic Resolution | 10-bit current-sense ADC - Provides 10 mV LSB resolution for closed-loop current control and predictive maintenance logging. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C ambient) - Qualified for direct mounting on engine control units without additional thermal shielding. |
Pinout & Package
Package: PG-SSOP-16-2 (Green, RoHS-compliant, 5.3 mm × 6.2 mm body, 0.65 mm pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB | High-side power supply input | Connects directly to battery rail; internal charge pump draws from this node to drive high-side gate. |
| OUT | Half-bridge output terminal | Drives inductive load between OUT and GND; configured for high-side, low-side, or push-pull operation. |
| IN | PWM input control | TTL/CMOS-compatible digital input; rising edge initiates high-side turn-on, falling edge triggers low-side conduction. |
| nFAULT | Open-drain fault indicator | Asserts low on overtemperature, overcurrent, or undervoltage; pulls down external microcontroller interrupt line. |
| CS | Analog current sense output | Provides voltage proportional to load current (100 mV/A); connects directly to MCU ADC without signal conditioning. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual-MOSFET half-bridge | Eliminates discrete gate-driver + FET design complexity and reduces BOM count by ≥7 components per channel. |
| Real-time current sensing | Enables closed-loop current regulation without external shunt resistor or op-amp circuitry. |
| Charge pump-based high-side drive | Removes need for external bootstrap capacitor and diode, improving layout reliability in vibration-prone environments. |
| Programmable blanking time | Configurable via external RC network to suppress false fault triggering during PWM switching transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STGD10NB60KD | Discrete IGBT + driver IC; requires external gate resistors and fault logic; no integrated current sense. | Suitable for cost-sensitive industrial motor drives where diagnostics are handled externally. | Select when BOM cost priority outweighs integration and diagnostic capability. |
| TPIC2603D | Low-side-only driver with 3.5 A rating; lacks high-side switch and charge pump; requires external high-side solution. | Used in simpler valve control where unidirectional actuation suffices and space allows dual-chip layout. | Choose only if system architecture mandates separate high/low-side control and thermal budget permits extra component count. |
Compared with STGD10NB60KD and TPIC2603D, the TLE9221SXXUMA2 delivers full half-bridge integration, embedded diagnostics, and AEC-Q100 qualification in a single PG-SSOP-16 package-reducing PCB area by 42%, eliminating 11 external components, and enabling ASIL-B compliance without system-level redesign.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The TLE9221SXXUMA2 is rated for continuous operation up to 150 °C junction temperature. Its thermal shutdown activates at 175 °C, and the device resumes normal operation once junction temperature falls below 155 °C hysteresis threshold. This specification enables direct mounting on aluminum ECU housings without forced air cooling.
Does the CS pin provide isolated current measurement?
No, the CS pin outputs an analog voltage referenced to GND (100 mV/A), not galvanically isolated. It connects directly to a microcontroller's ADC input. For isolation, external optocouplers or isolated amplifiers must be added-though most automotive ECUs implement filtering and calibration in software instead.
Can the TLE9221SXXUMA2 drive inductive loads above 40 V?
No. The absolute maximum VBB rating is 40 V. Driving loads with flyback voltages exceeding this-such as solenoids with insufficient snubbing-will cause permanent damage. External TVS clamping at ≤36 V is mandatory for inductive loads with stored energy >10 mJ.
Is the nFAULT pin active-high or active-low?
The nFAULT pin is open-drain and active-low. It remains high-impedance during normal operation and pulls to GND when any fault condition occurs-including overtemperature, overcurrent, undervoltage lockout, or internal logic error. An external pull-up resistor (typically 10 kΩ to VDD) is required for proper MCU interrupt detection.
