Overview
The RT9712BGF is a dual high-side power distribution switch manufactured by Richtek Technology Corporation. It integrates two N-channel MOSFETs with a typical on-resistance of 90 milliohms, designed for heavy capacitive loads and short-circuit protection. The device operates within a supply voltage range of 2.7V to 5.5V and features an internal charge pump requiring no external components. Key electrical parameters include a maximum output current of 1A per channel, reverse blocking capability, and under-voltage lockout. It is housed in a compact SOT-23-6 package.
Feature Summary
- Integrates two independent high-side N-MOSFET switches with low on-resistance for efficient power distribution.
- Includes an internal charge pump to control rise and fall times, minimizing current surges during switching without external components.
- Provides comprehensive protection against short circuits, overcurrent, and reverse current conditions.
Applications
- Power distribution systems requiring multiple switches in a single package
- Heavy capacitive load applications
- Short circuit protection circuits
Procurement Notes
Verify the specific suffix 'BGF' against official datasheets to confirm pinout and packaging details. Ensure compatibility with system voltage requirements between 2.7V and 5.5V. Confirm RoHS compliance status through manufacturer documentation before integration into final designs.
Selection Notes
Select this component when space-constrained designs require dual high-side switching capabilities. The integrated charge pump simplifies layout by eliminating external drive components. Consider the 90mΩ on-resistance for thermal management in high-current scenarios compared to higher resistance alternatives.
Part Context
This part belongs to the RT9712 series of power-distribution switches from Richtek. It is designed to replace discrete MOSFET solutions, offering reduced board space and improved performance in power management applications. The series supports various packages including SOT-23-6.
Replacement Considerations
Check for direct substitutes such as the RT9711 series or other dual high-side switches from compatible manufacturers. Verify pin-to-pin compatibility and ensure equivalent on-resistance and current handling capabilities.
