TPS22918TDBVRQ1: Single-Channel, 5.5V, 2A Load Switch with Adjustable Rise Time and Quick-Output Discharge
The TPS22918TDBVRQ1 is a highly integrated, single-channel load switch designed for automotive and industrial applications requiring precise power control. Operating across an input voltage range of 1V to 5.5V, it supports a maximum continuous current of 2A with an ultra-low on-resistance of 52mΩ (typical at 5V input), minimizing power loss and thermal dissipation. The device features adjustable rise time via an external capacitor (CT pin), enabling controlled turn-on to reduce inrush current and prevent voltage droop in systems with large capacitive loads. Additionally, its configurable Quick-Output Discharge (QOD) pin ensures rapid discharge of the output when disabled, facilitating safe power sequencing and system shutdown. The TPS22918TDBVRQ1 is housed in a compact, 6-pin SOT-23 package, making it ideal for space-constrained designs.
The TPS22918TDBVRQ1's low quiescent current (8.3µA typical at 3.3V input) extends battery life in portable or always-on systems, while the high-side N-channel MOSFET architecture ensures compatibility with a wide range of supply voltages. The device also supports functional safety design, with documentation available to aid in system-level safety certifications. Applications include automotive infotainment systems, ADAS modules, industrial automation, and portable electronics where efficient power management and protection are critical.
