OUT9 and 10 are for SH and have the stable start characteristics because of rapid charge and discharge circuits.
OUT10 and 11 are for AE.
At standby, the ISH pin voltage is put into the discharge condition by an internal transistor and set to 0 V.
ISH pin is also in the discharge condition (for rise compensation) when IN1 - 8 are entered.
The Vref voltage is 1.0 V with 1NHD = "L" and 0.67 V with 1NHD = "H."
8. Considerations for Design
(1) Constant-current setting (ISH, IAE, RFG1, 2, OUT9 to 12)
The constant current between OUT9 and OUT10 is set from the ISH input voltage and RFG1 connection resistance.
Control is made so that the voltage generated at a current detection resistor connected between RFG1 and GND is equal to the
ISH input voltage as shown in the block diagram. The output current is calculated as follows:
(Output current between OUT9 and OUT10) = (ISH input voltage)
