产品概述
描述
The SPV1050 is an ultra-low power and high-efficiency power manager embedding four MOSFETs for boost or buck-boost DC-DC converter and an additional transistor for the load connection/disconnection. An internal high accuracy MPPT algorithm can be used to maximize the power extracted from PV panel or TEG. The internal logic works to guarantee tight monitoring of both the end-of-charge voltage (VEOC) and the minimum battery voltage (VUVP) by opening the pass-transistor at triggering of the VEOC threshold or at triggering of the VUVP threshold to preserve the battery life. Both the VEOC and VUVP thresholds can be trimmed by external resistors connected between the STORE rail and the EOC and UVP pins, respectively. In boost configuration (CONF pin connected to the supply source), the IC requires 550 mV and 30 μA to Cold start; while after the first start-up the input voltage can range between 150 mV and VEOC. In buck-boost configuration (CONF pin connected to ground), the IC requires 2.6 V and 5 μA at Cold start; while after the first start-up input voltage can range between 150 mV up to 18 V. The STORE pin is available as unregulated voltage output (e.g. to supply by external LDO a micro-controller), while two fully independent LDOs (1.8 V and 3.3 V) are embedded for powering other companion ICs like MCU, sensors or RF transceivers. Both LDOs can be independently enabled through the related pins.
