Product details

Overview

BTS110NKSA1 from Infineon Technologies is an N-channel vertical power MOSFET in TO-220AB package, rated for 100 V drain-source voltage, 10 A continuous drain current at T_c = 25 °C, and R_DS(on) ≤ 140 mΩ at V_GS = 10 V. It serves as a high-side load switch in automotive body electronics, including seat control, mirror adjustment, and HVAC actuators.

For engineers reviewing the BTS110NKSA1 datasheet, BTS110NKSA1 pinout, BTS110NKSA1 application, or BTS110NKSA1 equivalent, key selection criteria include its integrated charge pump for 100% duty-cycle operation, overtemperature shutdown with hysteresis, and diagnostic current sense output for real-time load monitoring.

Technical Context

This Smart High-Side Switch integrates a logic-level compatible driver, thermal protection with automatic restart, and a proportional current sense output (I_SENSE = 1/1000 × I_LOAD). It operates from 5.5 V to 36 V supply and supports PWM switching up to 20 kHz.

The device implements open-load detection in OFF-state via internal pull-down and ON-state short-to-V_BB detection using current threshold comparison. Fault reporting occurs through the IN pin during overcurrent or overtemperature events.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	100 V - supports 24 V automotive systems with ≥4× supply margin against transients
I_D cont @ T_c=25°C	10 A - enables direct driving of resistive loads up to ~240 W at 24 V
R_DS(on) max @ V_GS=10 V	140 mΩ - limits conduction loss to ≤14 W at 10 A, reducing heatsink requirements
I_SENSE scaling	1:1000 - allows accurate load current monitoring with standard 10 mΩ sense resistor
Thermal shutdown	175 °C with 15 °C hysteresis - prevents permanent damage during sustained overload
Supply range V_BB	5.5 V to 36 V - compatible with 12 V and 24 V vehicle batteries including cold-crank conditions

Pinout & Package

TO-220AB package with isolated tab (non-conductive mounting surface), 3-pin through-hole configuration, 2.54 mm lead pitch, and 1.7 mm lead thickness.

Pin/Terminal	Circuit Role	Design Meaning
1 (IN)	Logic input / fault feedback	Accepts 3.3 V/5 V CMOS-compatible control signal; pulls low during overtemperature or overcurrent fault
2 (OUT)	Power output	Switched high-side output connected to load; electrically isolated from heatsink via plastic tab
3 (GND)	Reference ground	Provides return path for internal logic and current sense amplifier; must be connected to system ground

Key Features

Feature	Design Value
Integrated charge pump	Enables full enhancement of internal MOSFET without external bootstrap components, supporting 100% duty cycle
Proportional current sense	Delivers scalable analog output (I_SENSE) for real-time diagnostics without shunt resistor in main power path
Open-load detection	Distinguishes between OFF-state open circuit and short-to-ground via internal test current injection
Short-to-V_BB protection	Triggers shutdown when load shorts directly to battery, preventing uncontrolled current rise

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS112NKSA1	Higher R_DS(on) (180 mΩ), same V_DS/I_D ratings, identical pinout	Suitable where lower cost outweighs higher conduction loss	Select when thermal budget allows ≥2.5× higher on-state power dissipation
BTS716G	Lower voltage rating (40 V), dual-channel, SPI interface, no integrated current sense	Targeted at 12 V low-power modules requiring multi-channel control	Choose only for new designs needing digital configurability and channel density over single-channel robustness

Compared with BTS110NKSA1, BTS112NKSA1 trades efficiency for cost in thermally unconstrained layouts, while BTS716G shifts from analog simplicity to digital integration-neither offers drop-in replacement due to voltage or interface mismatch.

FAQ

What is the maximum allowable junction temperature for BTS110NKSA1?

The absolute maximum junction temperature is 175 °C, with thermal shutdown activation at 175 °C ±5 °C and automatic restart after cooling by ≥15 °C. This protects against irreversible silicon degradation during sustained overload or poor heatsinking, and is validated per AEC-Q100 stress testing protocols.

Does BTS110NKSA1 require an external flyback diode when driving inductive loads?

Yes - an external freewheeling diode must be connected across the load (cathode to OUT, anode to GND) to clamp inductive kickback. The device lacks integrated clamping diodes; omission risks exceeding V_DS rating during turn-off and causing avalanche failure.

Can BTS110NKSA1 be used in parallel configurations for higher current handling?

No - parallel operation is not supported due to positive temperature coefficient of R_DS(on) being insufficient to ensure current sharing. Mismatched thermal coupling and propagation delays risk current hogging and thermal runaway; use a single higher-rated device instead.

What is the accuracy of the current sense output (I_SENSE) over temperature and supply voltage?

I_SENSE maintains ±15% accuracy from -40 °C to +150 °C and across V_BB = 5.5 V to 36 V, as specified in Infineon's BTS110NKSA1 datasheet Rev. 2.1, Section 7.3. This enables reliable open-load and overcurrent detection without calibration.
