The recommended bias supply voltage range for TPS7H60x5 is from 10V to 14V. The input voltage supply for the driver should be well regulated and properly bypassed for best electrical performance. The BOOT voltage which supplies the high-side driver should be between 8V to 14V. It is imperative to minimize the voltage drop along the bootstrap charging path so that the high-side driver does not inadvertently enter into undervoltage lockout at any time during normal operation.

A local bypass capacitor must be placed between the VIN and AGND pins. Likewise, the bootstrap capacitor should be placed between the BOOT and ASW pins, and must also be in close proximity to the device. This capacitor must be located as close as possible to the device. TI recommends a low-ESR, low-ESL, ceramic, surface-mount capacitors (X7R or better) for the connections at VIN and BOOT.
