The TS2026 is a high-side MOSFET switch optimized for general-purpose power distribution requiring circuit protection.
The TS2026 is a high-side MOSFET switch optimized for general-purpose power distribution requiring circuit protection. It features two thermally isolated channels, each capable of delivering at least 500mA continuous current with an operating range of 2.7V to 5.5V.
Key protective features include internal current limiting, thermal shutdown, and under-voltage lockout (UVLO). The device includes a fault status output flag that asserts during over-current or thermal shutdown conditions, with transient faults internally filtered to prevent false assertions.
| Operating Voltage Range | 2.7V to 5.5V |
|---|---|
| On-Resistance (Max) | < 140mΩ per channel |
| Continuous Current (Min) | 500mA per channel |
| Operating Temperature Range | -20°C to +85°C |
| Short-Circuit Output Current Limit (Max) | 4.25A |
The device operates in an ambient temperature range of -20°C to +85°C.
Thermal shutdown shuts off the output MOSFET if the die temperature reaches 140°C while in current limit, and resets when it cools to 120°C.
The FLG signal is an active-low open-drain output that asserts during over-current or thermal shutdown conditions.
