BD39042MUF-C

General Description

Key Specifications

BD39042MUF-C is a supervisor IC with quad power good,

Watchdog timer and reset. This IC enables existing

system to improve its ASIL level easily.

◼ VDD Input Voltage Range:

2.7 V to 5.5 V

(VDD voltage level needs to be fixed within this range

in 6 % accuracy to avoid RSTIN reset detection)

◼ Detection Voltage (VDD POR / Power Good)

BD39042MUF-C includes built-in self-test (BIST).

Under Voltage Detection:

Over Voltage Detection:

Reset Assertion Delay Time:

-6 % (1.4 % accuracy)

+6 % (1.4 % accuracy)

10 ms

Features

◼ AEC-Q100 Qualified^{(Note 1)}

Power Good Assertion Delay Time:

10 ms

◼ Functional Safety Supportive Automotive Products

◼ Quad Power Good for External Inputs

◼ Over Voltage Detection (OVD)

◼ Under Voltage Detection (UVD)

◼ Adjustable Window Watchdog Timer(WDT)

◼ Reset for VDD Input (POR)

◼ Operating Temperature Range:

-40 °C to +125 °C
