TS2026L is a dual-channel power distribution switch optimized for general-purpose power distribution requiring circuit protection. It is internally current limited and has thermal shutdown that protects the device and load. When a thermal shutdown fault occurs, the output is latched off until the faulty load is removed. Removing that load or toggling the enable input will reset the device output. Both devices employ soft-start circuitry that minimizes inrush current in applications where highly capacitive loads are employed. A fault status output flag is asserted during over current and thermal shutdown conditions. Transient faults are internally filtered.
The TS2026L is a high-side MOSFET switch optimized for general-purpose power distribution requiring circuit protection. The device features two channels that are internally current limited and include thermal shutdown to protect the device and load from damage due to short-circuit faults or overheating.
Key characteristics include a maximum on-resistance of 140mΩ per channel, an operating voltage range of 2.7V to 5.5V, and a minimum continuous current capability of 500mA per channel. The device employs soft-start circuitry to minimize inrush current for highly capacitive loads and includes under-voltage lockout and reverse current flow blocking.
| Max On-Resistance per Channel | 140mΩ |
|---|---|
| Operating Voltage Range | 2.7V to 5.5V |
| Min Continuous Current per Channel | 500mA |
| Supply Voltage (VIN) | +6 V max. |
| Fault Flag Current | 25 mA |
The output is latched off until the faulty load is removed or the enable input is toggled.
Both devices employ soft-start circuitry to minimize inrush current.
The fault status output flag has a 3ms filter to eliminate false assertions.
