Dual high-side power switch with integrated protection
The Texas Instruments TPS2062DR is a dual-channel high-side N-channel power switch designed for general-purpose load switching in 2.7 V to 5.5 V systems. Each channel delivers up to 1 A continuous output with a typical on-resistance of 70 mΩ, minimizing voltage drop and power loss. The device integrates fixed current limiting, over-temperature protection, and undervoltage lockout (UVLO) to guard the load and supply against fault conditions. A status flag output provides a logic-level fault indication, and the switch is controlled via an active-high On/Off interface with non-inverting input logic. Packaged in an 8-SOIC (3.90 mm width) for surface-mount assembly, the TPS2062DR operates over a -40°C to 125°C junction temperature range, suiting industrial, telecom, and automotive cabin environments.
Protection set: current limit, thermal shutdown, UVLO
Fault protection is built in without external sense resistors or complex circuitry. The fixed current limit prevents damage from short circuits or overloads; the over-temperature shutdown protects the die if the junction exceeds the thermal threshold; and UVLO holds the switch off until the input supply rises above the minimum operating voltage. A status flag (open-drain, active-low) asserts during over-current or thermal fault conditions, which can be tied to a microcontroller GPIO or a pull-up resistor for system monitoring.
Industrial temperature grade and package
Rated for -40°C to 125°C junction temperature, the TPS2062DR is qualified for outdoor telecom base stations, factory automation I/O modules, and automotive cabin electronics (non-AEC-Q100, but the temperature range aligns with many industrial-grade designs). The 8-SOIC package is a standard footprint for low-power switches, and the device is MSL 1 (moisture sensitivity level not explicitly stated, but typical for TI SOIC — verify with the datasheet for reflow profiles).
Active lifecycle — no LTB risk
This makes it suitable for both new designs and ongoing production without supply disruption concerns. The part is ROHS3 compliant.
