Dual-Channel Power Distribution Switch
Pin assignment:
1. ENA 5. OUTB
2. FLGA 6. GND
3. FLGB 7. IN
4. ENB 8. OUTA
140mΩ max. on-resistance per channel
2.7V to 5.5V operating range
Under voltage lockout
General Description
www.DataSheet4TUh.ecoTmS2026 is high-side MOSFET switches optimized for general-purpose power distribution requiring circuit protection.
The TS2026 are internally current limited and have 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 device employ soft-start circuitry that minimized inrush current in application
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.
Features
140mΩ max. on-resistance per channel
2.7V to 5.5V operating range
500mA min. continuous current per channel
Short-circuit protection with thermal shutdown
Thermal isolated channels.
Fault status flag with 3ms filter eliminates false
assertions.

Note 3. Devices are ESD sensitive. Handing precautions recommended.
Note 4. For maintenance RDS≤140mΩ assembly to make gold conductors in diameter 50m.
Note 5. If there is a fault on one channel, that channel will shut down when the die reaches approximately 140 oC. If the
die reaches approximately 160 oC, both channels will shut down, even if neither channel is in current limit.
