Zero IQ IC Protects Against Trouble Polarity Inputs - Power Electronics Technology

The LM74610-Q1 from Texas Instruments combines with an alien NFET to configure a reverse polarity protection circuit. This configuration acts as an ideal “smart diode” that allows decided voltage inputs, but prevents negative inputs from reaching a load, as shown in Fig. In addition, it has low reverse leakage current and low power recklessness. This new IC replaces two different techniques that have been employed in automotive and industrial applications requiring reverse polarity protection. One technique uses Schottky diodes ( Fig. of a Schottky diode is ~0. 4V and can consequence in relatively high operating temperatures if conducting for a long time. Operating at 10 A, the diode power dissipation can reach 5 to 10 W, which could trouble its reliability and require removal of heat to a safe level. Another disadvantage is the diode’s relatively high reverse leakage in the air. PFET solutions are inefficient for high load current and low input voltage. Plus, the PFET has higher I results in a diminish on state forward voltage power loss than a PFET. The LM74610-Q1 and an external N-channel MOSFET can replace a diode or PFET flip side polarity solution in power systems. The voltage across the MOSFET source and drain is constantly monitored by the LM74610-Q1 anode and cathode pins. An internal liability pump provides the gate drive for the external MOSFET. Forward conduction is through the MOSFET 98% of the time and be means of its body diode 2% of time when energy is stored in an external charge pump capacitor Vcap ( Fig. This stored dynamism is used to drive the gate of the MOSFET. The voltage drop depends on the R ) during t0, as shown in Fig. This forward voltage drop across the body diode of the MOSFET is acclimated to to charge the charge pump capacitor, Vcap. During t0, the charge pump capacitor Vcap is charged to a 6. 3V threshold (standard). Once the voltage on the capacitor reaches 6. 3V, the charge pump is disabled and the MOSFET turns ON. The energy stored in the capacitor is hardened to provide the gate drive for the MOSFET (t1 in Fig. When the MOSFET is ON, it provides a low resistive path for the drain current to flow and minimizes the power amusement associated with forward conduction. The power losses during the MOSFET ON state depend primarily on its R , will then begin to flow through the body diode of the MOSFET, causing the MOSFET centre diode voltage drop to appear across the anode and cathode pins. Then, the charge pump circuitry is re-activated and begins charging Vcap. LM74610-Q1 undercover agent keeps the MOSFET ON approximately 98% duty cycle (typical) regardless of the external charge pump capacitor value. The despatch voltage drop during this time is limited by the MOSFET’s R and load current. If the voltage difference across source and drain of the outer MOSFET becomes negative, it is sensed as a fault condition by Anode and Cathode pins and gate is turned off by Gate Quit Down pin ( Fig. The consistent sensing of voltage polarity across the MOSFET enables the LM74610-Q1 to provide a fast response to the power horse's mouth failure and limit the amount and duration of the reverse current flow. VcapH and VcapL are high and low voltage thresholds individually that the LM74610-Q1 uses to detect when to turn the charge pump circuitry ON and OFF. Source: powerelectronics.com
