PRODUCTION DATA
The TPS7H60x3-SP contains three internal linear regulators: BP5L, BP7L, and BP5H. BP5L and BP7L are included on the low side of the driver. These linear regulators provide 5 V and 7 V, respectively, as the nominal output voltages. BP5L is used to power the low-side logic circuitry as well as the low-side gate drive voltage. The BP5L regulator has an accuracy of 5 V +3.5%/-5% to provide the proper voltage for driving GaN FETs. A minimum capacitor of 1 μF is required from the BP5L pin to PGND. BP7L powers the low-side transmitters within the driver. A minimum capacitor of 1 μF is also required from the BP7L pin to AGND.
On the high side, the voltage on BOOT serves as the input to the high side linear regulator BP5H. Similar to BP5L on the low-side, this regulator is used to power the high-side logic circuitry while providing the 5-V +3.5%/-5% high-side gate voltage to the external FET. A minimum capacitor of 1 μF is required from BP5H to PSW. The recommendation for all internal linear regulators is that these not be externally loaded other than where indicated within this document.
