TPS4H000-Q1 Descripción general
A smart high-side switch is a power management IC that connects a load to a positive supply rail through a MOSFET, providing protection and diagnostic functions. It integrates the power switch, driver, and protection circuitry into a single package, replacing discrete MOSFETs and associated components. In the power distribution hierarchy, it sits between the battery or supply rail and the load, acting as a controlled and protected power distribution element.
Key features include a wide operating voltage range of 3.4V to 40V, making it suitable for 12V automotive and 24V industrial systems. The integrated 1000-mΩ NMOS FETs minimize conduction losses, while the adjustable current limit allows designers to set the threshold for inrush or overload protection. Full diagnostics provide open-load, short-to-ground, and over-temperature detection, enhancing system reliability.
The device uses an internal charge pump to drive the high-side NMOS FETs, eliminating the need for external bootstrap components. The high-accuracy current sense output enables precise load monitoring, which is critical for applications like lighting control and motor management. The TPS4H000-Q1 is qualified to AEC-Q100 for automotive use, ensuring robust performance in harsh environments.
Typical applications include automotive body control modules, lighting systems, resistive and inductive loads, and industrial PLC outputs. Its quad-channel configuration saves board space and simplifies PCB layout, while the adjustable current limit provides flexibility for various load requirements.
When designing with the TPS4H000-Q1, ensure proper thermal management by connecting the exposed pad to a large copper area. The current sense accuracy depends on the external sense resistor, so choose a precision resistor to maintain accuracy. Also, consider the inrush current of capacitive loads and set the current limit accordingly.

Diferenciadores clave

- Quad-channel integration (frente a BTS7004-1EPA)
Notas de diseño
The TPS4H000-Q1's power dissipation is calculated as P = I^2 * RON. At 750mA per channel and 1000 mΩ, each channel dissipates 0.56W. With four channels, total dissipation can reach 2.25W. The HTSSOP package's exposed pad must be soldered to a large copper area to keep junction temperature below 125°C. Use thermal vias to connect to inner layers for better heat spreading.
Place a 100nF ceramic capacitor close to each VBB pin and a 10µF bulk capacitor at the supply input. The current sense pin (SNS) should have a sense resistor connected to ground with Kelvin connections to maintain accuracy. Keep the ILIM resistor close to the pin and avoid long traces to prevent noise coupling.
Do not exceed the absolute maximum input voltage of 40V. When driving inductive loads, ensure a freewheeling diode is placed across the load to clamp voltage spikes. The adjustable current limit must be set above the normal load current but below the maximum rating to avoid nuisance trips. Also, ensure the enable pin is properly pulled up or down to avoid unintended operation.
