The IW657P-18-50B with PMIC - Supervisors TDFN-14 RoHS is a high-performance, integrated system supervisor IC manufactured by Dialog Semiconductor. It is designed for use in automotive and industrial applications. This IC provides an integrated voltage monitor, reset logic, and tolerance monitoring function in a single package. It can monitor up to two system voltages and has a low active power consumption. It has an active-low Reset Output (RESET) signal for resetting the microcontroller or processor, and an active-low reset signal to other internal devices. It also has a programmable Reset Timeout (TOUT) and an integrated voltage tolerance monitor to provide protection against overvoltage, undervoltage, and reverse voltage conditions. Additionally, the IW657P-18-50B is RoHS-compliant, RoHS-compliant hardware features an automotive-grade performance along with an ability to operate over the extended operating temperature range of-40 to 125 °C.
