Description

BTS3134NHUMA1 is a single-channel automotive high-side switch with an integrated MOSFET. It is used to switch power from a battery to a load under MCU control, in 12–24 V automotive environments. The UMA1 variant denotes a specific package/packing option for this device.
Key features (typical):
- Internal MOSFET plus protection features
- Logic input/control (EN/IN) for load enable
- Overcurrent/short-circuit protection
- Undervoltage lockout and thermal shutdown
- Reverse polarity protection (as applicable)
- Diagnostic/status output to feed back load faults to a microcontroller
Typical applications:
- Driving loads like LED lighting, sensors, actuators, or small DC motors in automotive electronics
- Power distribution where protection and simple control are required
Notes:
- Verify exact electrical characteristics, pinout, and protection limits in the BTS3134NHUMA1 datasheet for your design.

Features

Key features of BTS3134NHUMA1:
- 1-channel smart high-side switch with integrated driver
- Wide automotive input range: typically 5–60 V
- Built-in current limit and protection against short-circuits
- Overcurrent/short-to-GND and short-to-VBAT protection
- Undervoltage (UVLO) and overvoltage protection
- Overtemperature (thermal shutdown) with safe-state
- Reverse polarity/short-to-battery protection
- Diagnostics: fault/status indication (DIAG/open-load, short, UVLO, overtemp)
- Slew-rate control on turn-on for EMI reduction
- Low quiescent current in OFF state
- Suitable for automotive-grade applications (robust, small package)

Package

The BTS3134NHUMA1 uses the UMA package: an 8‑pin, surface‑mount power package (UMA1 variant).

Pinout

- Pin count: 8 pins (HTSSOP/SOP-8 package).
- Function: BTS3134NHUMA1 is an automotive high-side smart switch with current limiting and diagnostics. It provides a switched output to a load from VIN, with:
- IN: control input
- OUT: load connection
- IS: current-sense output
- DIAG/STAT: diagnostic/status output (open-drain)
- EN/SHDN: enable input
- VIN/GND: power supply and ground
- NC: no-connect/substrate pin
It also includes protection features such as overcurrent, undervoltage, thermal shutdown, and reverse polarity protection.

Manufacturer

Manufacturer: Infineon Technologies AG.
What kind of company: A German multinational semiconductor company that designs and makes power and signal semiconductors for automotive, industrial, security, and digital applications.

Application

BTS3134NHUMA1 is a high-side switch IC. Typical applications:
- Automotive body/electrical systems for LED lighting and powered actuators
- Control of small DC motors, solenoids, and pumps
- MCU-controlled loads requiring built-in protection (overcurrent, undervoltage, overtemperature) and diagnostic feedback
