Product details
Overview
BTN9970LVAUMA1 from Infineon is an AEC-Q100 Grade 1 qualified high-current PN half-bridge IC integrating a p-channel high-side MOSFET, n-channel low-side MOSFET, and driver IC in one sTOLL package. It delivers typ. 9.7 mΩ on-resistance at 25°C, supports 8–18 V supply (up to 40 V transient), provides 60 A min overcurrent detection, and features adjustable slew rate for EMI optimization - used in automotive 12 V brushed DC motor control for fuel pumps and power liftgates.
For engineers reviewing the BTN9970LVAUMA1 datasheet, BTN9970LVAUMA1 pinout, BTN9970LVAUMA1 application, or BTN9970LVAUMA1 equivalent, key selection criteria include integrated protection (overcurrent/overtemperature/undervoltage), current sense + temperature/slew rate feedback via IS pin, logic-level IN/INH interface, and elimination of external charge pump due to p-channel high-side architecture.
Technical Context
The BTN9970LVAUMA1 implements a monolithic half-bridge with chip-on-chip integration of three die: p-channel HS MOSFET, n-channel LS MOSFET, and dedicated driver IC on a common lead frame. Its p-channel HS switch enables charge-pump-free operation, reducing board area and EME generation.
Control logic includes programmable dead time, eight selectable slew rates, and status flag reporting via IS pin for real-time current sensing (±5% accuracy), junction temperature monitoring, and active slew rate level indication - all synchronized with fault latching and automatic restart on undervoltage recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 8 V – 18 V nominal; withstands up to 40 V transient - enables direct connection to automotive battery without external regulation. |
| HS + LS RDS(on) | Typ. 9.7 mΩ @ 25°C; max. 18.1 mΩ @ 150°C - ensures <1.5 W conduction loss at 30 A continuous output. |
| Overcurrent Threshold | Min. 60 A - triggers fast shutdown before bond wire or die damage under short-circuit conditions. |
| Quiescent Current | Max. 3.3 µA @ 85°C - supports always-on vehicle modules with negligible standby drain. |
| Protection Functions | Integrated overtemperature latch, undervoltage restart, cross-conduction prevention, and short-circuit detection - eliminates need for external supervision circuitry. |
| Slew Rate Options | Eight discrete settings - allows EMI tuning per motor cable length and EMC class requirements (CISPR 25 Class 3/5). |
Pinout & Package
Package: PG-HSOF-7-1 (sTOLL), thermally enhanced exposed-pad SOIC variant with integrated heat sink capability; footprint compatible with automated SMT assembly and high-power thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,2) | Ground reference | Common return path for logic, power, and sense circuits; must be low-inductance PCB plane connection. |
| IN | Logic input | Controls bridge state: HIGH = LS ON / HS OFF; LOW = HS ON / LS OFF; internal pull-down ensures safe default. |
| INH | Inhibit enable | Active-low enable: LOW forces tristate (both switches OFF); internal pull-down prevents spurious turn-on. |
| IS | Diagnostic output | Open-drain analog/digital multiplexed signal: proportional current sense voltage, temperature code, or slew rate level - requires external RC filter and ADC input. |
| VS (Pins 6,7) | Power supply input | High-current input for both MOSFET sources; pins internally bonded together - must route with ≥1 mm trace width. |
| OUT (Pin 8, EP) | Power output | Switching node connecting HS drain and LS source; exposed pad serves as primary thermal path and current return. |
Key Features
| Feature | Design Value |
|---|---|
| Charge-pump-free p-channel HS | Eliminates external capacitor and associated layout complexity while maintaining fast turn-on speed and low EME. |
| Integrated current sense | Monitors load current with ±5% accuracy across -40°C to 150°C - enables closed-loop torque control without shunt resistor. |
| Programmable slew rate | Eight discrete dV/dt settings via external resistor on IS pin - balances switching loss vs. radiated emissions in final system layout. |
| Multi-fault diagnostic flag | Single-pin IS output encodes current, temperature, slew rate, and fault status - reduces BOM count and routing congestion. |
| AEC-Q100 Grade 1 qualification | Validated for operation from -40°C to +125°C ambient, with 150°C junction limit - meets automotive powertrain and body electronics requirements. |

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) (15 mΩ typ), no integrated current sense, fixed slew rate | Lacks IS pin diagnostics; requires external shunt and comparator for current monitoring | Choose when cost sensitivity outweighs diagnostic needs and thermal margin permits higher conduction loss. |
| TPIC2603D | External gate drivers required; separate HS/LS MOSFETs; no integrated protection logic | Demands full discrete design including dead-time control, fault handling, and thermal management | Prefer only for legacy designs where discrete flexibility justifies added BOM and validation effort. |
Compared with BTN7960B and TPIC2603D, BTN9970LVAUMA1 reduces total solution size by 40%, cuts diagnostic component count by 3–5 parts, and guarantees AEC-Q100 Grade 1 compliance out-of-box - making it optimal for new automotive body electronics platforms targeting ASIL-B functional safety alignment.

FAQ
What is the maximum continuous output current rating for BTN9970LVAUMA1?
The device supports continuous output current up to 30 A at TA = 125°C with proper PCB copper area (≥200 mm² 2 oz Cu per side) and forced airflow. Peak pulsed current reaches 60 A for ≤10 ms, limited by overcurrent detection threshold and thermal response time - not a sustained rating.
How does the IS pin provide current, temperature, and slew rate information simultaneously?
The IS pin outputs a time-multiplexed analog voltage: 0.5–2.5 V represents sensed current (1 V/A scale), 0.1–0.5 V encodes junction temperature (10 mV/°C), and discrete voltage levels (e.g., 2.7 V, 3.0 V) indicate active slew rate setting - decoded by MCU ADC sampling at ≥10 kHz with known timing sequence per datasheet Figure 24.
Is external dead time required when using BTN9970LVAUMA1?
No. Internal logic generates fixed 400 ns dead time between HS and LS switching transitions to prevent shoot-through. This value is factory-trimmed and temperature-compensated - no external timing components or MCU delay insertion is needed for safe operation.
Can BTN9970LVAUMA1 drive inductive loads without external freewheeling diodes?
Yes. The integrated MOSFETs include body diodes rated for continuous freewheeling current up to 30 A. For high-dV/dt or high-frequency PWM (>20 kHz), external Schottky diodes are recommended to reduce reverse recovery losses and improve efficiency - but not required for basic operation.
