Description

The A4405 is an automotive power management IC that uses a high frequency constant on-time 5.45 V pre-regulator to supply two internal 5 V linear regulators and a 3.3 V linear DMOS driver. Designed to supply CAN and microprocessor power supplies in high temperature environments, the A4405 is ideal for under hood applications. Efficient operation is achieved by using a buck pre-regulator to efficiently drop the input voltage

before supplying the linear regulators; this reduces power dissipation and increases overall regulator efficiency.



Features and Benefits

• AEC Q100 Grade 0 qualified

• Internal buck pre-regulator followed by LDO outputs

• 5.5 to 36 V VIN operating range (50 V maximum);

for start/stop, cold crank, and load dump requirements

• 2.2 MHz constant on-time buck regulator

• Valley current sensing achieves shortest buck on-times

• 50 V absolute maximum input voltage for surges

• 5.5 to 46 V input voltage range

• −40ºC to 150ºC junction temperature range

• Power-on reset (NPOR pin) with adjustable rising delay

• 5 V (V5P pin) internal low dropout tracking linear regulator with both overcurrent foldback and short-to-battery protection

• 5 V (V5 pin) internal low dropout linear regulator with overcurrent foldback protection

• 3.3 V (V33 pin) external linear regulator DMOS driver with a programmable current limit (up to 500 mA) and overcurrent foldback protection

• Logic enable input (ENB pin)

• Ignition enable input (ENBAT pin)

• Ignition status indicator (ENBATS pin)

• Buck pulse-by-pulse overcurrent protection

• Buck LX short circuit protection (latched)

• Missing asynchronous diode protection (latched)

• Switcher (VREG pin), 3.3 V (V33 pin), and charge pump (VCP pin) undervoltage lockout protection (UVLO)

• Thermal shutdown protection (TSD)



Applications:

Automotive Control Modules, such as:

• Electronic power steering (EPS)

• Transmission control (TCU)

• Antilock braking (ABS)

• Emissions control
