BM1Z102FJ BM1Z103FJ Description of Blocks – continued 2. DC Voltage Monitor Circuit
This IC monitors the voltage between the VH_DC and GND pins. It converts the voltage and outputs analog voltage from the DCOUT pin. The VH_DC pin has a built-in 600 V withstand voltage monitor circuit. It realizes high reliability and low power consumption. 5.0 4.5 ] V[ 4.0 T U O C 3.5 DV :e 3.0 g atl 2.5 o V n 2.0 Pi TU 1.5 O C D 1.0 0.5 0.0 0 50 100 150 200 250 300 350 400 450 500 550 600 VH_DC Pin Voltage: VVH_DC [V] Figure 11. DCOUT Pin Voltage vs VH_DC Pin Voltage When a capacitor is connected to the DCOUT pin as an external component, it is necessary to attach a resistance like Figure 9.
