27 / 158 page  www.austriamicrosystems.com Revision 1v13 26 - 157 AS3658 Data Sheet Confidential - Detail ed Descri ption-Power Management Functions 8.2.1 High voltage Current Sinks (DCDC_CURR1, DCDC_CURR2 and DCDC_CURR3) Current sinks DCDC_CURR3, DCDC_CURR1 and DCDC_CURR2 can be controlled individually. The step-up DCDC converter may supply them with voltages up to 15V. If any of these current sinks is used, connected VCURR_GPIO to a supply with at least 3.0V Table 13. Current Sinks Characteristics Symbol Parameter Min Typ Max Unit Note . Table 14. DCDC_CURR1 Current sink current bit definition Addr: 39 DCDC_CURR1 Value This register controls the current value of the dcdc_curr1 current sink Bit Bit Name Default Access Description Table 15. DCDC_CURR2 Current sink current bit definition Addr: 40 DCDC_CURR2 Value This register controls the current value of the dcdc_curr2 current sink Bit Bit Name Default Access Description IDCDC_Curr1,2,3 DCDC_CURR1,2 and DCDC_CURR3 current, 00h-3Fh 0 38.25 mA For V(DCDC_CURRx) > 0.45V resolution = 0.15mA IDCDC_protect Current sink protection Current 2µA Protection Current if stpup2_on=1 and dcdc_currx_current=00h Δ absolute Accuracy -5 +5 % All Current sinks VDCDC_CURR1, VDCDC_CURR2, VDCDC_CURR3 Voltage compliance 0.45 15 V during normal operation 7:0 dcdc_curr1_current 00h R/W Defines the current into DCDC_CURR1 if enabled by dcdc_curr1_ctrl 00h power down (default state) 01h 0.15mA (LSB) ....
