TB9004FNG Description

Short technical summary and product information.

The Toshiba TB9004FNG is a BiCMOS integrated circuit designed for automotive applications, specifically for 3.3/2.5/1.5V microcomputer systems. This dual-voltage regulator incorporates two constant-voltage power outputs, VCC1 and VCC2, along with comprehensive system reset functions.

 

VCC1 offers selectable output voltages of 3.4V, 2.5V, or 1.5V, utilizing an external output transistor and allowing for a variable current limiter set by an external resistor. VCC2 provides a fixed 5.0V output, also using an external transistor with a variable current limiter.

 

For system reset capabilities, both power outputs are equipped with a low-voltage monitor, a power-on reset function, and a watchdog timer. The device also features W/D stop control for managing the watchdog timer. It operates within a wide temperature range of -40°C to 125°C and is housed in a compact 24-pin SSOP package with a 0.65mm pitch.

 

With a low current consumption, the TB9004FNG is suitable for power-sensitive automotive designs. In stop mode (both outputs off), it consumes 0 μA. In standby mode (VCC1 ON, VCC2 OFF), consumption is 150 μA typical, and in active mode (both outputs ON), it is 300 μA typical.
