TDA16888 - Infineon Technologies

TDA16888 High Performance Power Combi Controller

Power Supply The TDA 16888 is protected against overvoltages typically above 17.5 V by an internal Zener diode Z3 at pin 9 (VCC) and against electrostatic discharging at any pin by special ESD circuitry. By means of its power management the TDA 16888 will switch from internal stand-by, which is characterized by negligible current consumption, to operation m.
