MC33998DW Detalhes do produto

The 33998 is a medium-power, multi-output power supply integrated circuit that is capable of operating over a wide input voltage range, from 6.0 V up to 26.5 V with 40 V transient capability.

It incorporates a sensorless current mode control step-down switching controller regulating directly to 5.0 V. The 2.6 V linear regulator uses an external pass transistor to reduce the 33998 power dissipation. The 33998 also provides a 2.6 V linear standby regulator and two 5.0 V sensor supply outputs protected by internal low resistance LDMOS transistors.

There are two separate enable pins for the main and sensor supply outputs and standard supervisory functions such as resets with power-up reset delay. The 33998 provides proper power supply sequencing for advanced microprocessor architectures such as the MPC5xx and 683xx microprocessor families.



Features

• Operating Voltage Range 6.0 V up to 26.5 V (40 V transient)

• Step-Down Switching Regulator Output VDDH = 5.0 V @ 1400 mA (total)

• Linear Regulator with External Pass Transistor VDDL = 2.6 V @ 400 mA

• Low-Power Standby Linear Regulator VKAM = 2.6 V @ 10 mA

• Two 5.0 V @ 200 mA (typical) Sensor Supplies VREF Protected

   Against Short-to-Battery and Short-to-Ground with Retry Capability

• Undervoltage Shutdown on the VDDL, VDDH Outputs with Retry Capability

• Reset Signals

• Power-Up Delay

• Enable Pins for Main Supplies (EN) and Sensor Supplies (SNSEN)

• Power Sequencing for Advanced Microprocessor Architectures

• Pb-Free Packaging Designated by Suffix Code EG
