The Texas Instruments TPS4H000BQPWPRQ1 is a quad-channel automotive smart high-side switch integrating four NMOS power FETs with approximately 1Ω on-resistance at 25°C. It is designed for resistive, capacitive, and inductive loads such as LEDs, relays, sensors, cameras, and automotive sub-modules. TI currently lists the TPS4H000-Q1 family as ACTIVE.
TI specifies a wide operating-voltage feature range of 3.4V to 40V, while the recommended operating-condition table specifies a 4V to 40V supply range. The nominal DC load-current rating is 0.75A per channel, with thermal performance depending on ambient temperature, PCB layout, and load conditions.
The exact B version provides an analog current-sense output, unlike the A version that uses open-drain status outputs. Current-sense accuracy is specified at ±15% for load currents above 5mA, with higher accuracy at larger currents. An external resistor can also set the current-limit threshold, with approximately ±20% current-limit accuracy for loads of 100mA and above under the specified conditions.
Integrated protection includes short-to-ground current limiting, thermal shutdown, thermal-swing protection, inductive-load negative-voltage clamping, loss-of-ground protection, and loss-of-battery protection. Diagnostic functions detect overcurrent, short-to-ground, open-load, and short-to-battery faults, while a global FAULT signal provides rapid system notification.
The TPS4H000BQPWPRQ1 is AEC-Q100 qualified, Grade 1, with an ambient operating range of -40°C to +125°C. It is supplied in a 20-pin thermally enhanced HTSSOP (PWP) package on a 2,000-piece large tape-and-reel, with MSL Level 3 classification. TI lists the exact orderable part as Active Production.
