Product details
Overview
TLE94106ESXUMA1 from Infineon is a six-channel automotive-grade half-bridge driver IC designed for DC motor control in HVAC flap actuation, mirror adjustment, and relay driving. It features six independently diagnosable half-bridge outputs, 16-bit SPI interface with daisy-chain capability, and integrated protection including overcurrent (0.9 A min), open-load detection (HS/LS), and overtemperature pre-warning. Operates from 5.5–18 V supply with 0.1 µA quiescent current in sleep mode.
For engineers reviewing the TLE94106ESXUMA1 datasheet, TLE94106ESXUMA1 pinout, TLE94106ESXUMA1 application, or TLE94106ESXUMA1 equivalent, key selection criteria include SPI-controlled PWM operation at 80/100/200 Hz, dual supply rails (VS1/VS2), exposed-pad thermal package (PG-TSDSO-24), and AEC-Q100 qualification for under-hood automotive use.
Technical Context
The device implements six independent high-side/low-side driver stages with charge-pump-based gate drive, enabling full forward/reverse/brake/high-Z motor control via 16-bit SPI commands. Each output includes dedicated current sensing, temperature monitoring, and short-circuit detection logic tied to a global error flag.
Diagnosis is performed in real time: open-load detection operates in ON-state for all six channels; selectable thresholds apply to HS1/HS2; cross-current protection prevents shoot-through during switching transitions; and VS undervoltage/overvoltage lockout (5.5–20 V functional range, 40 V load dump tolerance) ensures robust power domain supervision.
Key Specifications

Pinout & Package
Package: PG-TSDSO-24 (24-pin thermally enhanced fine-pitch SOIC with exposed die pad). Exposed pad (EP) must be connected to GND for optimal thermal and EMC performance; electrical ground is provided by pins 1 and 12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 12, EP | GND | Power and signal ground reference; EP is thermal/EMC pad, not electrically isolated |
| 2, 3, 10, 11, 14, 23 | OUT1–OUT6 | Half-bridge output terminals - each drives one motor winding or relay coil |
| 5, 7, 8, 19, 20 | SDI, SDO, EN, CSN, SCLK | SPI control interface - enables daisy-chained configuration and fast diagnosis |
| 6 | VDD | 3.0–5.5 V logic supply - tolerant of 3.3 V or 5 V microcontroller I/O |
| 16, 21 | VS1, VS2 | Main power supply inputs - must be externally shorted; powers all six half-bridges |
| 4, 9, 13, 15, 17, 18, 22, 24 | N.C. | No-connect pins - left open or grounded for layout compatibility with family variants |
Key Features
| Feature | Design Value |
|---|---|
| Independent Output Diagnostics | Per-channel overcurrent, open-load (ON-state), and short-to-battery/ground detection with status register reporting |
| Selectably Thresholded Open-Load Sensing | Configurable thresholds on HS1/HS2 allow optimization for varying motor coil resistances |
| Low-Power Sleep Mode | 0.1 µA quiescent current enables permanent connection to battery in automotive body electronics |
| Robust Power Domain Protection | Combined over/undervoltage lockout, cross-current prevention, and 40 V load dump tolerance |
| Thermally Optimized Packaging | PG-TSDSO-24 with exposed pad reduces junction-to-board thermal resistance for sustained 1.8 Ω RDS(on) per side |
Applications
| HVAC Flap Actuation | Side Mirror Adjustment |
|---|---|
|
Use Scenario: Precise positioning of HVAC air flaps in vehicle cabin climate systems using bidirectional DC motors. IC Role / Device Role / Timing Role: Six-fold half-bridge driver executing forward/reverse/brake commands via SPI; provides real-time open-load feedback during movement. Use Value: Eliminates need for external sense resistors or discrete protection circuits while maintaining AEC-Q100 compliance for under-dash mounting. |
Use Scenario: Simultaneous x-y positioning and fold/unfold control of power side mirrors in premium automotive platforms. IC Role / Device Role / Timing Role: Drives two independent DC motors (x/y axis) and a third for folding; uses PWM at 100 Hz for smooth low-speed motion. Use Value: Single-chip solution replaces three dual-H-bridge ICs, reducing PCB area and BOM count without sacrificing diagnostic coverage. |
| Monostable/Bistable Relays | Automotive LED Load Control |
|
Use Scenario: Driving monostable (pulse-actuated) and bistable (latching) relays in central body control modules. IC Role / Device Role / Timing Role: Provides controlled current pulse (via HS/LS sequencing) and monitors coil continuity via open-load diagnostics. Use Value: Enables automatic relay health monitoring and failure logging without additional test circuitry or firmware overhead. |
Use Scenario: Dimmable LED lighting control for interior ambient lighting or exterior signaling functions requiring current regulation. IC Role / Device Role / Timing Role: Configured in LED mode with PWM-driven constant-current sink; uses internal current control loop instead of external shunt. Use Value: Supports flicker-free dimming at 200 Hz with 8-bit resolution while delivering up to 0.9 A per channel without external MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar six-channel half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE94112EL | Twelve-channel variant in same PG-TSDSO-36 package; identical SPI protocol and protection features | Targets systems requiring >6 motor/relay loads on single board; higher pin count and larger footprint | Select when scaling from 6 to 12 outputs without redesigning control firmware or diagnostics logic |
| BTS724G | Single-channel high-side switch with integrated diagnostics; no low-side or SPI interface | Requires six separate ICs and external MCU GPIO/SPI handling; lacks daisy-chain capability | Choose only for legacy designs where distributed control and minimal channel integration are preferred |
Compared with TLE94106ESXUMA1, TLE94112EL offers double the channel count in a larger package but identical feature set and pin-compatible control architecture, whereas BTS724G requires significant system-level redesign to replicate basic functionality and lacks integrated multi-channel coordination.

FAQ
What is the maximum allowable supply voltage during load dump events?
The TLE94106ESXUMA1 supports up to 40 V on VS1/VS2 during load dump transients, as specified in its absolute maximum ratings. This rating is validated per ISO 7637-2 Pulse 5a and enables direct connection to automotive battery rails without external TVS clamping in most applications.
Can the device drive inductive loads without external freewheeling diodes?
Yes - the internal half-bridge structure includes integrated body diodes and active clamp circuitry that safely recirculate inductive kickback current during PWM off-times. No external flyback diodes are required for standard DC motor or relay coil loads within rated current limits.
How does open-load detection work in ON-state for high-side and low-side outputs?
During active drive, the device measures voltage drop across the conducting FET and compares it against programmable thresholds. For HS outputs, it checks for expected VDS < 1.5 V; for LS outputs, it verifies VDS < 0.8 V. Deviation indicates open-circuit conditions and triggers diagnostic flags in the status register.
Is daisy-chain SPI operation supported with mixed TLE94xx devices?
Yes - all TLE94xx family members (including TLE94106ES, TLE94108EL, TLE94110EL, and TLE94112EL) share identical SPI frame format, command set, and daisy-chain timing. Devices can be cascaded regardless of channel count, with status data shifted out through SDO in sequence.
