Electrical Parameters

In terms of electrical specifications, the N-channel MOSFET of AO4616A features a 30V drain-source voltage rating, fully meeting the requirements of single-cell lithium battery power supply systems.Its continuous drain current is 12A at 25℃, and drops to 8A at an ambient temperature of 100℃.Regarding on-resistance: typical RDS(on) is below 14mΩ at VGS=10V, and below 21mΩ at VGS=4.5V.

The P-channel MOSFET also supports 30V withstand voltage. It delivers a continuous current of 10A at 25℃ and 4.6A at 100℃.Its on-resistance is lower than 23mΩ at VGS=-10V, and lower than 28mΩ at VGS=-4.5V.


Compared with similar P-channel devices, such low on-resistance helps reduce static power loss.In terms of switching characteristics, the N-channel gate charge is 5.2nC and the P-channel is 10nC, both delivering excellent switching response speed.The thermal resistance values are 46.3℃/W for the N-channel and 50℃/W for the P-channel, matching the standard thermal performance of SOP-8 packages and facilitating thermal management design.

Application Scenarios

The package and parameter specifications of AO4616A suit multiple typical applications.In battery protection circuits, the N-channel MOSFET acts as the discharge path switch, while the P-channel controls the charging path, a widely adopted configuration in mainstream lithium battery protection board designs.For load switching applications, the complementary MOSFET features simple gate control logic, easily cooperating with main control ICs to manage power-on sequences.In power management, it can be used as both low-side and high-side switches, meeting on-off control requirements for low-power loads.Its 30V voltage margin withstands transient overvoltage up to 12V and 24V common in consumer electronic products.
