DATASHEET AEM10330
PIN NUMBER Function NAME QFN40 Configuration pins R_MPP[0] 15 R_MPP[1] 12 Used for the configuration of the MPP ratio. R_MPP[2] 11 T_MPP[0] 30 Used for the configuration of the MPP timings. T_MPP[1] 32 LOAD_CFG[0] 24 LOAD_CFG[1] 25 Used for the configuration of LOAD output voltage VLOAD. LOAD_CFG[2] 26 STO_CFG[0] 33 STO_CFG[1] 34 Used for the configuration of the threshold voltages for the STO_CFG[2] 35 energy storage element (VOVDIS, VCHRDY and VOVCH). STO_CFG[3] 27 - Pul ed up to VINT: storage device (STO) has highest priority at start-up. STO_PRIO 29 - Pul ed down to GND: load (LOAD) has highest priority at start-up. STO_OVCH 23 Used for the configuration of the threshold voltages (VOVDIS, VCHRDY and VOVCH) for the STO_OVDIS 21 energy storage element when STO_CFG[3:0] are set to custom mode (optional). Must be left floating if not used. STO_RDY 22 - Pul ed up to LOAD: SLEEP STATE enabled. EN_SLEEP 39 - Pul ed down to GND: SLEEP STATE disabled. - Pul ed up to VINT: al ows charges flowing directly from SRC to STO when EN_STO_FT 31 SRC is above 5V. - Pul ed down to GND: normal operation. - Pul ed up to LOAD: enables the charging of the storage element. EN_STO_CH 20 - Pul ed down to GND: disables the charging of the storage element. - Pul ed up to VINT: HIGH POWER MODE enabled. EN_HP 28 - Pul ed down to GND: HIGH POWER MODE disabled. PRIM_CUT 5 Used for the configuration of the primary battery. Must be left floating if not used. PRIM_FB 6 Used for the configuration of the primary battery. Must be connected to GND if not used. Other 10, 14, 16 GND Ground connection, best possible connection to PCB ground plane.
