BTS3134NHUMA1

BTS3134NHUMA1 is Infineon’s smart high-side switch from the BTS family, designed for automotive and other 12/24 V systems. A microcontroller can drive the IN pin to switch the OUT path to a load (lamp, motor, relay) while the device provides protection and diagnostics.
Key features
- Integrated load switch with current limitation
- Protections: overcurrent/short to GND, short to VS, thermal shutdown, undervoltage lockout
- Diagnostic/status output to indicate fault or normal operation
- Slew-rate control to reduce EMI on turn-on/off
Typical applications
- Automotive lighting, powered accessories, seat/motor actuators, relays and other inductive/resistive loads
Note
Exact electrical specs (voltage range, current limit, pinout) depend on the package variant. Check the official datasheet for your specific BOM details.

Here are typical features of the BTS3134NHUMA1 (automotive high-side switch family). For exact specs, consult the datasheet.
- Automotive-grade high-side load switch with integrated protection
- Built-in current limiting and short-circuit protection
- Undervoltage lockout (UVLO)
- Overtemperature protection (thermal shutdown)
- Diagnostic/Status output for fault indication
- Enable input to turn the switch on/off
- Soft-start to limit inrush and EMI
- Reverse polarity protection and load-dump robustness
- ESD protection and rugged packaging (UMA1)
- Suitable for 12V/24V automotive applications
Note: Verify exact channel count, voltage ranges, and current limits in the official datasheet.

- Pin count: 8 pins (8-pin package, e.g., HVSON/SO-8)
- Function: Single-channel automotive high-side switch with integrated MOSFET and protection. It routes VBAT to the load via OUT under control from IN (and/or EN/DIAG). Includes current limiting and protections (OC, UVLO, thermal) and provides diagnostic/status and sense/limit pins for load current monitoring.

Manufacturer: Infineon Technologies AG.
What kind of company: A German multinational semiconductor manufacturer that designs and produces microelectronics and system solutions for automotive, industrial, power, and security applications.

BTS3134NHUMA1 is a high-side switch for DC loads used in automotive and industrial apps. Typical areas:
- Automotive body electronics: lighting (head/tail/interior), wipers, sunroof, HVAC blower
- Motors and actuators: window lifters, seat adjusters, pumps
- Relays replacement: fed from MCU with protection
- General 12–48 V DC load control with built-in protection
Features implied: MCU-controlled input, protection against short to ground and overcurrent/thermal, with diagnostics and PWM/dimming capability for controlled loads.

BTS3134NHUMA1 uses an 8‑pin Ultra‑Compact UMA package (about 3×3 mm).
