SBASAO0A May 2023 – September 2023 AMC130M03
PRODUCTION DATA
Basic electrostatic discharge (ESD) circuitry protects the AMC130M03 inputs from ESD and overvoltage events in conjunction with external circuits and assemblies. Figure 8-3 shows a simplified representation of the ESD circuit. The protection for input voltages exceeding VHLDO_OUT can be modeled as a simple diode.
The AMC130M03 has an integrated negative charge pump that allows for input voltages below HGND with a unipolar supply. Consequently, shunt diodes between the inputs and HGND cannot be used to clamp excessive negative input voltages. Instead, the same diode that clamps overvoltage also clamps undervoltage at the reverse breakdown voltage. Take care to prevent input voltages or currents from exceeding the limits provided in the Absolute Maximum Ratings table.
