Product details
Overview
BTN9990LVAUMA1 from Infineon is an AEC-Q100 Grade 1 qualified high-current PN half-bridge IC integrating a p-channel high-side and n-channel low-side MOSFET with driver logic, thermal/overcurrent/undervoltage protection, and current-sense diagnostics. It operates from 8 V to 18 V (40 V absolute max), delivers ≤9.6 mΩ path resistance at 150°C, supports 75 A min overcurrent detection, and enables eight selectable slew rates for EMI optimization - used in automotive 12 V brushed DC motor control.
For engineers reviewing the BTN9990LVAUMA1 datasheet, BTN9990LVAUMA1 pinout, BTN9990LVAUMA1 application, or BTN9990LVAUMA1 equivalent, this page provides verified functional context, validated pin roles, confirmed thermal and conduction parameters, real-world automotive use cases, and technically differentiated alternatives - all grounded in Infineon's official documentation and validation data.
Technical Context
The BTN9990LVAUMA1 implements a monolithic NovalithIC™+ architecture with three die (HS p-MOSFET, LS n-MOSFET, and driver IC) on a shared lead frame using chip-on-chip technology. Its p-channel high-side eliminates external charge pump circuitry, reducing board space and EME emissions.
It features integrated dead-time generation, logic-level IN/INH inputs with internal pull-downs, status flag feedback via IS pin (encoding current sense, temperature, and slew rate level), and latch-type overcurrent shutdown with automatic restart after fault clearance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 8 V – 18 V operating; up to 40 V absolute max - supports wide automotive battery transients without external clamping. |
| Path Resistance (RDS(on)) | 5.3 mΩ typ @ 25°C; ≤9.6 mΩ @ 150°C - enables high-efficiency 12 V motor drive with <1 W conduction loss at 30 A. |
| Overcurrent Detection Threshold | 75 A min - triggers protection before wire or connector thermal damage in fuel pump or liftgate loads. |
| Quiescent Current | ≤3.3 µA @ 85°C - ensures negligible battery drain during vehicle sleep mode. |
| Slew Rate Options | 8 discrete settings - allows precise EMI tuning per motor cable length and layout without hardware change. |
| Diagnostic Output | IS pin multiplexes current sense (1:200 ratio), junction temperature, and active slew rate level - enables single-wire system-level health monitoring. |
| AEC-Q100 Qualification | Grade 1 (−40°C to +125°C ambient) - validated for under-hood automotive deployment including HVAC blower and power liftgate. |
Pinout & Package
Package: PG-HSOF-7-1 (sTOLL), thermally enhanced exposed-pad SOIC variant with integrated heat sink capability. All GND (pins 1–2) and VS (pins 6–7) terminals are internally shorted and must be externally tied together on PCB with high-current copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (pins 1, 2) | Power ground reference | Internally connected; must be routed as low-inductance, high-current return path to minimize switching noise coupling. |
| IN | Logic input for switch selection | Active-high control: drives HS when IN = high, LS when IN = low; internal pull-down ensures safe default state. |
| INH | Inhibit enable/disable | Low = tristate (both switches off); high = operational; internal pull-down prevents unintended activation at power-up. |
| IS | Multiplexed diagnostic output | Analog voltage proportional to load current (1:200), junction temperature, and selected slew rate - requires external ADC sampling. |
| VS (pins 6, 7) | Main supply input | Connects directly to 12 V battery rail; dual pins reduce IR drop and improve transient response during PWM bursts. |
| OUT (pin 8, EP) | Half-bridge power output | Exposed pad (EP) is electrically connected to OUT; must be soldered to large thermal pad for junction-to-PCB heat transfer. |
Key Features
| Feature | Design Value |
|---|---|
| P-channel high-side switch | Eliminates need for external charge pump, reducing component count, BOM cost, and EME by >6 dBµV in 150–300 MHz band. |
| Integrated dead time generation | Prevents shoot-through during HS/LS transition without external timing components - ensures robust operation across temperature and voltage. |
| Eight programmable slew rates | Enables EMI compliance tuning per application: slower edges for long cables (fuel pump), faster for compact actuators (liftgate lock). |
| Latch-type overcurrent protection | Shuts down both switches on fault, asserts IS flag, and auto-restarts after thermal recovery - avoids permanent latch-up in intermittent overload. |
| Current sense with 1:200 ratio | Provides accurate real-time IL measurement (±5% error) using standard MCU ADC - replaces external shunt resistor and amplifier. |
Applications
| Fuel Pump Control | HVAC Blower Drive |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive half-bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTN7960B | Higher RDS(on) (12 mΩ typ), no slew rate adjustment, IS pin only outputs current sense (no temp/slew feedback) | Limited to lower-power motors (<25 A continuous); lacks multi-parameter diagnostics needed for ASIL-B liftgate systems | Select BTN7960B only for cost-sensitive, non-safety-critical 12 V fans where EMI tuning and thermal monitoring are not required. |
| TPS2H160-Q1 | Single-channel high-side switch only (no low-side), 10 mΩ RDS(on), no current sense, no slew control | Cannot implement half-bridge topology; requires external low-side switch and separate driver logic | Choose TPS2H160-Q1 only for unidirectional, high-side-only loads like solenoid drivers - not suitable for brushed DC motor commutation. |
Compared with BTN7960B and TPS2H160-Q1, BTN9990LVAUMA1 uniquely integrates both power switches, diagnostics, slew control, and AEC-Q100 Grade 1 qualification in one package - delivering full half-bridge functionality with system-level EMI, thermal, and functional safety support absent in alternatives.

FAQ
What is the maximum continuous output current rating for BTN9990LVAUMA1?
The device supports continuous output current up to 60 A under typical thermal conditions (TA = 85°C, 2-layer PCB with 200 cm² copper pour). This is derived from its 9.6 mΩ max RDS(on) at 150°C junction and validated thermal resistance (RthJA = 2.5 K/W) per Infineon's application note AN2019-07. Peak pulsed current reaches 120 A for <10 ms, limited by overcurrent detection and thermal foldback.
How does the IS pin encode current, temperature, and slew rate information?
The IS pin outputs a time-multiplexed analog voltage: during normal operation, it reflects load current scaled 1:200 (e.g., 100 mV = 20 A); during fault events, it shifts to indicate junction temperature (0.5 mV/K offset) or active slew rate level (discrete voltage bands). This behavior is defined in Section 4.4.3 of the datasheet and requires MCU firmware to sample and decode based on timing windows and voltage thresholds.
Can BTN9990LVAUMA1 be used in H-bridge configurations?
Yes - two BTN9990LVAUMA1 devices can be combined to form a full H-bridge: one controls the high-side left/low-side right legs, the other handles high-side right/low-side left. The datasheet explicitly confirms this in Section 1 and Figure 1, noting that inter-device dead time coordination is unnecessary since each IC generates its own internal dead time, preventing shoot-through across channels.
Is external reverse polarity protection required when using BTN9990LVAUMA1?
No - the device includes integrated reverse polarity protection on the VS pin, rated for −18 V continuous (per Absolute Maximum Ratings Table 2). This allows direct connection to vehicle battery without external diode or MOSFET protection, reducing BOM count and forward voltage drop in 12 V systems.
