Product details
Overview
TLE7182EMXUMA1 from Infineon Technologies is an automotive-grade H-bridge and dual half-bridge driver IC designed to control four external N-channel MOSFETs in high-current DC motor drives. It supports 0–95% duty cycle at 20 kHz for high-side outputs, 0–100% for low-side outputs, features integrated shoot-through protection, bootstrap charge pumps, reverse polarity protection drive (RPP), and analog current-sense OPAMP with overcurrent warning - deployed in electric power steering, radiator fans, and fuel pumps.
For engineers reviewing the TLE7182EMXUMA1 datasheet, TLE7182EMXUMA1 pinout, TLE7182EMXUMA1 application, or TLE7182EMXUMA1 equivalent, key selection criteria include bootstrap-capable high-side gate drive capability, SCDL-adjustable short-circuit detection, ERR pin diagnostics, shunt-based current sensing interface, and AEC-Q100 qualification for 12 V automotive power nets.
Technical Context
The TLE7182EMXUMA1 integrates two independent floating high-side/low-side driver stages with level-shifted gate drivers, each supporting continuous DC conduction and internal dead-time insertion to prevent shoot-through. Its bootstrap architecture enables high-side N-MOSFET operation without isolated supplies, while the RPP output drives an external reverse-polarity protection MOSFET.
Diagnostic functions include analog overcurrent detection via ISP/ISN inputs, fixed-threshold warning via ISO output, adjustable short-circuit levels via SCDL pin with open-detection, plus VS under-voltage shutdown, VREG under-voltage warning, VDH over-voltage warning, and junction temperature monitoring - all reported through a push-pull ERR pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 7.0 V to 34 V - supports full automotive battery range including cold-crank (5.5 V min functional) and load-dump transients |
| High-Side Duty Cycle | 0–95% at 20 kHz - enables precise PWM control of brushed DC motors with thermal-limited bootstrap recharge |
| Low-Side Duty Cycle | 0–100% - allows synchronous rectification or continuous conduction mode in motor phases |
| Quiescent Current | 8 µA at Tj = 25 °C, ENA low - enables ultra-low-power sleep mode for always-on vehicle subsystems |
| Output Sink/Source Resistance | RSink = 9 Ω, RSou = 13.5 Ω - defines gate drive strength for typical 10–50 nC automotive MOSFETs |
| Junction Temperature Range | −40 °C to +150 °C - qualified per AEC-Q100 Grade 0 for under-hood placement |
| Short-Circuit Detection | Analog-adjustable via SCDL pin with open-pin detection - allows system-level tuning of fault threshold without hardware change |
Pinout & Package
Package: PG-SSOP-24 (24-pin shrink small-outline package), thermally enhanced with exposed tab connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BH1, BH2 | Bootstrap capacitor positive terminal | Provides floating supply for high-side gate drivers; requires ≥330 nF ceramic capacitor per phase |
| GH1, GH2 | High-side gate driver output | Level-shifted push-pull output driving N-MOSFET gates up to 55 V drain-source |
| GL1, GL2 | Low-side gate driver output | Ground-referenced output capable of 100% duty cycle and fast turn-off |
| SH1, SH2 | High-side source connection | Connects to MOSFET source; used for high-side current sensing and level-shifting reference |
| SL | Common low-side source node | Single return path for both low-side MOSFET sources; enables shared shunt resistor placement |
| SCDL | Adjustable short-circuit detection input | Voltage-controlled threshold setting; open-circuit detection disables SCD function |
| ERR | Diagnostic status output | Push-pull active-high flag indicating any active fault (overtemp, UVLO, OC, SC, OV) |
| ISO | Current sense amplifier output | Analog voltage proportional to motor current; fixed gain enables direct ADC interface |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-phase control inputs | IH1/IL1 and IH2/IL2 allow fully asynchronous PWM timing for torque vectoring or regenerative braking |
| Integrated shoot-through protection | Hardware-enforced minimum dead time prevents cross-conduction during switching transitions |
| Reverse polarity protection drive (RPP) | Dedicated 25 mA output drives external N-MOSFET to block battery reversal damage in 12 V systems |
| Shunt-based current sensing | ISP/ISN differential inputs with rail-to-rail ISO output enable accurate motor current measurement down to milliohm shunts |
| AEC-Q100 Grade 0 qualification | Validated for −40 °C to +150 °C operation - suitable for engine bay and EPS module integration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge and dual half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BD94001FVJ-E2 | Single H-bridge only; no dual half-bridge mode; lacks RPP output and SCDL adjustability | Suitable for single-motor systems only; no reverse polarity protection drive capability | Select when only one bridge is needed and cost sensitivity outweighs diagnostic flexibility |
| DRV8305DCA | Integrated MOSFETs (not external); higher IQ (3 mA vs. 8 µA); no SCDL pin or RPP output | Targeted at BLDC FOC with integrated current sense; not compatible with discrete N-MOSFET topologies | Choose for space-constrained BLDC designs where integration reduces BOM count |
Compared with BD94001FVJ-E2 and DRV8305DCA, the TLE7182EMXUMA1 uniquely supports dual independent half-bridges with external N-MOSFETs, adjustable short-circuit thresholds, and dedicated reverse-polarity protection drive - making it optimal for multi-actuator automotive systems requiring field-serviceable power stages and granular fault diagnostics.

FAQ
What is the maximum allowable PWM frequency for continuous operation?
The TLE7182EMXUMA1 supports up to 20 kHz PWM with 95% high-side duty cycle under thermal constraints and ≥330 nF bootstrap capacitance. Higher frequencies reduce maximum duty cycle due to bootstrap capacitor recharge time; operation beyond 20 kHz requires derating based on thermal simulation and layout optimization.
How does the SCDL pin adjust short-circuit detection thresholds?
The SCDL pin accepts a DC voltage (0–6 V) that sets the short-circuit current threshold proportionally: 0 V disables detection, 6 V enables maximum sensitivity. An open-circuit condition on SCDL automatically deactivates short-circuit protection and asserts ERR, enabling fail-safe system response without external pull-up/down resistors.
Can the TLE7182EMXUMA1 drive P-channel high-side MOSFETs?
No - the TLE7182EMXUMA1 is designed exclusively for N-channel high-side MOSFETs using bootstrap gate drive. Its GHx outputs are level-shifted push-pull stages referenced to SHx, incompatible with P-MOSFET source-follower configurations. External level-shifting circuitry would compromise timing, protection, and AEC-Q100 compliance.
Is the ISO output ratiometric to supply voltage or absolute?
The ISO output is absolute and rail-to-rail, delivering a fixed-gain analog voltage (typically 1 V/A across shunt) independent of VS or VREG fluctuations. Its offset and gain are trimmed during production, enabling direct connection to 12-bit ADCs without calibration for motor current monitoring in automotive environments.
