7.3 Power Supply Recommendations

The RES60A-Q1 is a high-voltage resistor divider, with no active circuitry or protective diodes. There are no specific power-supply connection requirements other than respecting the limits expressed in Absolute Maximum Ratings and Recommended Operating Conditions.

To provide additional protection against high-edge-rate transient events, such as in applications requiring extremely high ESD ratings, consider implementation of a parallel path for high-frequency signal content by using multiple high-voltage capacitors connected in series from HVIN to LVIN. This parallel path acts to shunt the high-frequency signal and bypass the RES60A-Q1, dissipating the surge energy outside the device, without impacting the dc and low-frequency precision of the device. Verify that creepage and clearance requirements are respected, and be aware that additional input capacitance can extend system step-response settling times. A TVS diode at the MID pin provides additional clamping protection against fast transients for downstream low-voltage circuitry, if necessary.
