L99PM60J is a low power 5V single supply management IC, integrated with 5V low drop linear regulator, 2 high side drivers, 2 low side drivers, LIN2.1 transceiver and window watchdog, programmable reset threshold, VS monitoring/temperature measurement and other functions.
The L99PM60J is a power management system integrated circuit designed for automotive ECUs. It combines a low-dropout voltage regulator (100 mA) with a LIN 2.1 compliant transceiver to manage body control modules such as door zones.
The device features an ST SPI interface for mode control and diagnostics, including window watchdog functionality and advanced fail-safe mechanisms. It includes high-side and low-side drivers that are short-circuit protected and supports various operating modes like Flash, VBAT-standby, and VPAR-standby.
The device includes one 5 V low-drop voltage regulator capable of 100 mA in continuous mode.
No, no electrolytic capacitor is required on the regulator output; only a typical 220 nF ceramic capacitor is needed.
The ultra-low quiescent current in VBAT-standby mode is 7 µA.
