描述
The BD4xxS2-C series are low quiescent regulators featuring 45V absolute maximum voltage, and output voltage accuracy of ±2% (3.3V or 5.0V: Typ), 200mA output current and 40µA (Typ) current consumption. These regulators are therefore ideal for applications requiring a direct connection to the battery and a low current consumption. A logical “HIGH” at the CTL pin enables the device and “LOW” at the CTL pin not enables the device. (Only W: Includes switch) Ceramic capacitors can be used for compensation of the output capacitor phase. Furthermore, these ICs also feature overcurrent protection to protect the device from damage caused by short-circuiting and an integrated thermal shutdown to protect the device from overheating at overload conditions.

Description of Blocks

Block Name

Function

Description of Blocks

A logical “HIGH” (≥ 2.8 V) at the CTL pin enables the device

and “LOW” (≤ 0.8 V) at the CTL pin not enable the device.

CTL^{(Note 1)}

PREREG

TSD

Control Output Voltage ON/OFF

Internal Power Supply

Thermal Shutdown Protection

Reference Voltage

Power Supply for Internal Circuit

To protect the device from overheating.

If the chip temperature (Tj) reaches ca. 175 °C (Typ),

the output is turned off.

VREF

Generate the Reference Voltage

Drive the Output MOS FET

DRIVER

OCP

Output MOS FET Driver

Over Current Protection

To protect the device from damage caused by over current.

If the output current reaches ca. 550 mA (Typ),

the output current is limited.

(Note 1) Applicable for product with Enable Input.
