NCP5106A, NCP5106B High Voltage, High and Low Side Driver The NCP5106 is a high voltage gate driver IC providing two outputs for direct drive of 2 N−channel power MOSFETs or IGBTs arranged in a half−bridge configuration version B or any other high−side + low−side configuration version A. It uses the bootstrap technique to ensure a proper drive of the high−side power switch. The driver works with 2 independent inputs.

NCP5106A, Negative Voltage Safe Operating Area on the Bridge Pin Figure 52. NCP5106B, Negative Voltage Safe Operating Area on the Bridge Pin http://onsemi.com 15 NCP5106A, NCP5106B APPLICATION INFORMATION Negative Voltage Safe Operating Area When the driver is used in a half bridge configuration, it is possible to see negative voltage appearing on the bridge pin (pin 6) during the power MOSFETs transitions. When the high−side MOSFET is switched off, the body diode of the low−side MOSFET starts to conduct. The negative voltage applied to the bridge pin thus corresponds to the forward voltage of the body diode. However, as pcb copper tracks and wire bonding introduce stray elements (inductance and capacitor), the maximum negative voltage of the bridge pin will combine the forward voltage and the oscillations created by the parasitic elements. As any CMOS device, the deep negative voltage of a selected pin can inject carriers into the substrate, leading to an erratic behavior of the concerned component. ON Semiconductor provides characterization data of its half−bridge driver to show the maximum negative voltage the driver can safely operate with. To prevent the negative injection, it is the designer duty to verify that the amount of negative voltage pertinent to his/her application does not exceed the characterization curve we provide, including some safety margin. In order to estimate the maximum negative voltage accepted by the driver, this parameter has been characterized over full the temperature range of the component. A test fixture has been developed in which we purposely negatively bias the bridge pin during the freewheel period of a buck converter. When the upper gate voltage shows signs of an erratic behavior, we consider the limit has been reached. Figure 51 (or 52), illustrates the negative voltage safe operating area. Its interpretation is as follows: assume a negative 10 V pulse featuring a 100 ns width is applied on the bridge pin, the driver will work correctly over the whole die temperature range. Should the pulse swing to −20 V, keeping the same width of 100 ns, the driver will not work properly or will be damaged for temperatures below 125°C. • If the negative pulse characteristic (negative voltage Summary: level & pulse width) is above the curves the driver runs in safe operating area. • If the negative pulse characteristic (negative voltage level & pulse width) is below one or all curves the driver will NOT run in safe operating area. Note, each curve of the Figure 51 (or 52) represents the negative voltage and width level where the driver starts to fail at the corresponding die temperature. If in the application the bridge pin is too close of the safe operating limit, it is possible to limit the negative voltage to the bridge pin by inserting one resistor and one diode as follows: Vcc D2 U1 NCP5106A VCC IN_HI IN_LO GND MUR160 8 7 6 5 R1 10R M2 C1 100n Vbulk 1 IN_Hi IN_LO 0 2 3 4 M1 VBOOT DRV_HI BRIDGE DRV_LO D1 MUR160 0 Figure 53. R1 and D1 Improves the Robustness of the Driver R1 and D1 should be placed as close as possible of the driver. D1 should be connected directly between the bridge pin (pin 6) and the ground pin (pin 4). By this way the negative voltage applied to the bridge pin will be limited by D1 and R1 and will prevent any wrong behavior. http://onsemi.com 16 NCP5106A, NCP5106B PACKAGE DIMENSIONS SOIC−8 NB CASE 751−07 ISSUE AJ −X− A 8 5 B 1 S 4 0.25 (0.010) M Y M −Y− G K NOTES: 1.
