2.4V threshold, AEC-Q100 qualified
The BD52E24G-MTR is a single-channel voltage detector from ROHM's BD52Exxx-M series, qualified to AEC-Q100 for automotive applications. It monitors a single supply rail and asserts a reset when the voltage drops below 2.4V — the exact threshold for this variant. The output is active-low, open-drain, rated for the full -40°C to 105°C operating temperature range.
Package and footprint
Housed in a 5-pin SOT-753 (SC-74A) surface-mount package, also designated as 5-SSOP. The small footprint suits space-constrained automotive ECU and sensor module PCBs. The open-drain output requires an external pull-up resistor to the monitored or logic supply rail — the value sets the rise time and quiescent current.
Lifecycle and compliance
ROHS3 compliant. The AEC-Q100 qualification (grade 1 implied by the 105°C rating) means PPAP documentation is available through the supply chain for OEM submissions.
