BTS7008-2EPA 개요
A smart high-side switch is a power-management semiconductor that places a protected MOSFET channel between a load and its positive supply. Unlike a basic MOSFET or relay, it combines load switching, overcurrent and short-circuit handling, thermal protection, under-voltage lockout, reverse-voltage protection, and diagnostic feedback. The BTS7008-2EPA sits within the broader smart-power-switch hierarchy: power MOSFET, protected load driver, power-management IC, and discrete semiconductor.
The device provides two independently controlled output channels, an 8 mΩ RDS(on) rating, and support for automotive loads to 7.5 A. Protection includes overload, short-circuit, over-temperature, overvoltage, under-voltage lockout, and reverse-voltage functions. Current diagnosis through the IS signal enables a controller to distinguish operating conditions and detect channel faults, while the digital interface supports channel selection and protection-counter clearing.
Its diagnostic architecture is important because a protected switch must report why a load was disabled rather than acting as an opaque fuse. The manufacturer datasheet describes analog and digital diagnostic signals at IS, plus digital diagnosis and protection-counter control through DSEL-related signaling. The device also defines two overload thresholds selected according to the VDS condition, allowing protection behavior to adapt to the switching state.
Typical uses include automotive body electronics, seat and door modules, heating-control loads, lighting, pumps, solenoids, and other 12 V loads requiring local protection and feedback. The dual-channel organization reduces component count when two related loads share a module. Diagnostic current information can improve system observability and shorten fault investigation.
PCB design must preserve short, low-inductance power paths and place protection or diagnostic networks where their switching transients cannot couple into sensitive control signals. Designers should verify the exact pin assignment, exposed-pad connection, output layouts, and diagnostic thresholds in the manufacturer datasheet before releasing a production layout.
This page consolidates the verified manufacturer specifications, source links, protection functions, application guidance, and drop-in-replacement assessment. It also distinguishes confirmed facts from parameters not exposed in the supplied search data, preventing unsupported electrical or mechanical claims.

일반적인 애플리케이션
BTS7008-2EPA 적합 용도: 6 애플리케이션s: Automotive Body Control Loads, Seat and Door Control Modules, Heating and Thermal Control, Lighting and Indicator Loads, Pump and Solenoid Drivers, Industrial and Mobile 12 V Distribution.
Automotive Body Control Loads
The BTS7008-2EPA fits automotive body-control modules that switch pumps, valves, heaters, or similar 12 V loads through two protected channels. Its 8 mΩ RDS(on) helps reduce conduction loss, while load support to 7.5 A aligns with the stated automotive capability. Integrated overload, short-circuit, thermal, reverse-voltage, and under-voltage protection reduce the need for separate fuses in each load path. The IS diagnostic output lets the module controller distinguish normal operation from fault behavior, although the exact routing and threshold settings must follow the Infineon datasheet.
Seat and Door Control Modules
The dual-channel BTS7008-2EPA is appropriate for compact seat, latch, mirror, or door-control modules where two protected 12 V outputs simplify local distribution. The -40°C to +150°C specification covers a broad automotive temperature range, and the PG-TSDSO-14-22 surface-mount package supports board-level integration. Protection prevents a stalled motor or shorted actuator from becoming an uncontrolled board-level failure. Diagnostic feedback at IS can support service diagnostics, although module-specific fault logic and actuator flyback arrangements remain design requirements.
Heating and Thermal Control
Heater, blower, thermal-grid, or defrost relays can benefit from local switching and diagnosis through the BTS7008-2EPA. Its two channels allow related loads to be controlled independently, while 8 mΩ RDS(on) limits voltage drop and dissipation at the stated automotive-load capability. The device's short-circuit, overload, and over-temperature protection add layers of robustness around resistive or inductive loads. Designers must add or verify the appropriate load-switching network, particularly where an inductive load requires flyback energy control, and confirm thermal performance for the selected duty cycle.
Lighting and Indicator Loads
The BTS7008-2EPA can control protected 12 V lighting or indicator channels in vehicle and mobile equipment where remote switching and fault feedback are useful. Two channels reduce the number of discrete protection elements required when paired lamps or indicator loads share similar current requirements. Protection against overload, short circuit, reverse voltage, and undervoltage makes the switch appropriate for wiring environments where transient faults are possible. For LED or lamp loads, the final driver network must account for inrush, clamp behavior, and any source-dependent diagnostic response.
Pump and Solenoid Drivers
Small 12 V pumps and solenoids are typical loads for a protected smart high-side switch because their startup current and stall behavior can stress ordinary discrete drivers. The BTS7008-2EPA supports loads up to 7.5 A and includes overload, short-circuit, thermal, latch, and diagnostic functions. Its 8 mΩ RDS(on) helps preserve supply voltage during steady-state operation, while current diagnosis supplies feedback for detecting abnormal load behavior. The designer must still validate flyback energy, cable transients, switching frequency, and the actual load's cold and stalled current against the application limits.
Industrial and Mobile 12 V Distribution
The BTS7008-2EPA also fits non-automotive 12 V distribution equipment that benefits from two-channel protected switching, such as industrial control modules, battery-backed systems, and mobile electronics. The -40°C to +150°C operating range and integrated fault functions support robust load control, while the diagnostic interface improves observability compared with an unprotected relay or discrete MOSFET stage. Supply and load transients remain application-dependent, so designers should verify the electrical limits, external protection, and thermal performance in the official manufacturer datasheet.

주요 차별점
- Integrated diagnosis reduces reliance on external fault-only circuitry (vs A generic dual high-side MOSFET stage)
- Two-state-dependent overload thresholds (vs A basic fuse and discrete switch implementation)
- High automotive-load capability with low stated resistance (vs A standard 12 V relay without electronic diagnostics)
설계 노트
Use the shortest practical supply, output, and ground paths because the 8 mΩ switch still carries transient current during load switching. Follow the official BTS7008-2EPA application diagram for pin and exposed-pad treatment. Keep the two output nets separated as required by the intended load topology, and provide adequate copper area for both electrical performance and thermal spreading. The supplied search data does not expose exact copper-width or via-count recommendations, so those dimensions must be taken from the manufacturer layout guidance and current design rules.
Route the IS diagnostic connection away from high dV/dt output and supply nodes. Retrieved datasheet excerpts identify IS as a combined SENSE/IIS output and describe DSEL-controlled diagnosis and protection-counter clearing, so interface traces may carry both analog and digital information. Terminate or bias these nets exactly as shown in the current manufacturer application diagram. Incorrect filtering, grounding, or coupling can corrupt fault interpretation even when the power channel itself is operating normally.
Estimated conduction loss is calculated as P = I² × RDS(on). At 7.5 A and the verified 8 mΩ rating, the arithmetic is 0.45 W before adding switching, driver, and ambient-path effects; at 3 A it is 0.072 W. These are estimates based only on RDS(on), not manufacturer power-dissipation figures. Validate junction temperature with the datasheet thermal model, actual copper area, nearby heat sources, and the required -40°C to +150°C environmental context.
Do not treat 7.5 A support as permission to operate continuously at the absolute maximum under every thermal condition. Check inrush, motor starting current, stalled current, cable transients, and short-circuit behavior against the current datasheet limits. The overload thresholds are selected according to VDS, so control software and diagnostic thresholds must be coordinated with that behavior. Also verify any flyback or clamp strategy for inductive loads rather than assuming the smart switch replaces external energy-control components.
