SBVS343A March 2019 – September 2019 TPS7A78
Excessive reverse current can damage the TPS7A78. Reverse current flows through the intrinsic body diode of the pass-transistor instead of the normal conducting channel. At high magnitudes, this current flow degrades the long-term reliability of the device.
Conditions where reverse current can occur are:
If reverse current flow is expected in the application, external protection is recommended to provide protect. Reverse current is not limited within the device, so external limiting is required, as illustrated in Figure 30 and Figure 31, if extended reverse-voltage operation is anticipated.
