A, C: The A pin serves as the simulated diode anode and the C as the cathode. GATE is driven high when V(AC) exceeds 10 mV. Both devices provide a strong GATE pulldown when V(AC) is less than the programmable fast turnoff threshold. The TPS2412 has a soft pulldown when V(AC) is less than 10 mV but above the fast turnoff threshold. Several internal comparator and amplifier circuits monitor these two pins. The inputs are protected from excess differential voltage by a clamp diode and series resistance. If C falls below A by more than about 0.7 V, a small current flows out of C. Protect the internal circuits with an external clamp if C can be more than 6 V lower than A. The internal charge pump output, which provides bias power to the comparators and voltage to drive GATE, is referenced to A. Some charge pump current appears on A due to this topology. The A and C pins should be Kelvin connected to the MOSFET source and drain. A and C connections should also be short and low impedance, with special attention to the A connection. Residual noise from the charge pump can be reduced with a bypass capacitor at A if the application permits. BYP: BYP is the internal charge pump output, and the positive supply voltage for internal comparator circuits and GATE driver. A capacitor must be connected from BYP to A. While the capacitor value is not critical, a 2200-pF ceramic is recommended. Traces to this part must be kept short and low impedance to provide adequate filtering. CAUTION Shorting this pin to a voltage below A damages the TPS241x. Copyright © 2007–2015, Texas Instruments Incorporated Submit Documentation Feedback 9 Product Folder Links: TPS2412 TPS2413 |
