Pin Configuration Table 5. AD5100 Pin Function Descriptions Pin No. Mnemonic Description 1 V1MON High Voltage Monitoring Input. AD5100 internal supply is derived from V1MON. There must be a 10 μF electrolytic capacitor between this pin and GND, placed as close as possible to the V1MON pin. 2 GND Ground. 3 VOTP One-Time Programmable Supply Voltage for EPROM. A 10 μF decoupling capacitor (low ESR) to GND is required. 4 V3MON Low Voltage Monitoring Input. 5 MR Manual Reset Input. Active low. 6 WDI Watchdog Input. 7 SCL I2C Serial Input Register Clock. Open-drain input. If it is driven directly from a logic driver without the pull-up resistor, ensure that the VIH minimum is 3.3 V. 8 SDA I2C Serial Data Input/Output. Open-drain input/output. If it is driven directly from a logic driver without the pull- up resistor, ensure that the VIH minimum is 3.3 V. 9 RESET Reset. Push-pull output with rail voltage of V3MON. 10 V4OUT Open-Drain Output. Triggered by V4MON. 11 SHDNWARN Shutdown Warning. Active low, open-drain output. 12 SHDN Shutdown Output. Push-pull output with selectable rail voltage of V1MON or VREG, the AD5100 internal power (30 V maximum). 13 AD0 I2C Slave Address Configuration. If tied high, this pin can only be tied to 3.3 V maximum. 14 V4MON Low Voltage Monitoring Input. Capable of withstanding 30 V. 15 GND/NC Ground/No Connect. Can be grounded or left floating but do not connect to any other potentials. 16 V2MON High Voltage Monitoring Input. It is also the internal supply voltage enabling input. 1 2 3 4 16 15 14 5 13 6 12 7 11 10 8 9 AD5100 TOP VIEW (Not to Scale) GND Figure 4. Recommended PCB Layout for Shielded High Voltage Inputs |
