The TPS2014 and TPS2015 power distribution switches from TI are designed for applications where heavy capacitive loads and short circuits are likely to be encountered. The high-side switch is a 95-mΩ n-channel MOSFET. It is controlled by a logic enable that is compatible with 3-V and 5-V logic. The gate drive is provided by an internal charge pump that controls the power switch rise times and fall times to minimize current surges during switching. The charge pump requires no external components and allows operation from supplies as low as 4 V. When the output load exceeds the current-limit threshold or a short circuit is present, the TPS20xx limits the output current to a safe level by switching into a constant-current mode, and the overcurrent logic output is set to low. Continuous heavy overloads and short circuits will not cause damage. The switch features short-circuit protection, thermal protection, logic overcurrent output, enable input compatible with 3-V and 5-V logic, and more.
The TPS2014 and TPS2015 are high‑side MOSFET power distribution switches designed for heavy capacitive loads and short‑circuit conditions. They feature an internal charge pump, over‑current protection, thermal shutdown, and undervoltage lockout, with enable inputs compatible with 3‑V and 5‑V logic.
The devices are offered in 8‑pin SOIC and PDIP packages, operate from 0 °C to 125 °C, and support input voltages from –0.3 V to 7 V. Detailed electrical characteristics, absolute maximum ratings, and mechanical data are provided in the following sections.
| On‑state resistance (RON) | 95 mΩ |
