JAJSE48C August 2017 – April 2018 TAS5755M
PRODUCTION DATA.
The UVP and POR circuits of the TAS5755M fully protect the device in any power-up/down and brownout situation. While powering up, the POR circuit resets the overload circuit (OLP) and ensures that all circuits are fully operational when the PVDD and AVDD supply voltages reach 7.6 V and 2.7 V, respectively. Although PVDD and AVDD are independently monitored, a supply-voltage drop below the UVP threshold on AVDD or either PVDD pin results in all half-bridge outputs immediately being set in the high-impedance (Hi-Z) state.
