Product details

Overview

MC33889DDW from NXP Semiconductors is a system basis chip (SBC) integrating a 5.0 V/200 mA LDO regulator, low-speed fault-tolerant CAN transceiver (125 kbps), programmable watchdog, SPI interface, HS1 high-side switch (150 mA), and dual wake-up inputs. It operates in Normal, Standby, Stop, and Sleep modes and is designed for automotive body control modules requiring robust power management and CAN communication.

For engineers reviewing the MC33889DDW datasheet, MC33889DDW pinout, MC33889DDW application, or MC33889DDW equivalent, this page delivers verified specifications, mode-dependent current consumption (e.g., 55–90 µA in Sleep2), CAN threshold voltages (VDIFF1 = 3.5 V min for MC33889D), HS1 R_DS(ON) (≤5.0 Ω at 125 °C), and SPI timing compliance (4 MHz max).

Technical Context

The MC33889DDW implements a SMARTMOS-based architecture with integrated protection: overtemperature prewarning (130 °C) and shutdown (160–190 °C), supply fail detection (V_THRESH = 1.5–4.0 V), and battery fall early warning (6.1 V typical). Its CAN transceiver complies with ISO 11898-3 for fault-tolerant operation up to 125 kbps and supports TermVbat mode with single-ended wake-up on CANH/CANL.

Power sequencing is managed via SPI-controlled V2 regulator tracking (V2 = 1.0 × VDD1), HS1 switch activation (t_S-HSON ≤ 22 µs), and configurable watchdog periods (WD1–WD4 spanning 8.58 ms to 392 ms in Normal mode). The device uses internal oscillators (100 kHz nominal) and supports cyclic sense wake-up with eight timing options (CSFWU1–CSFWU8).

Equivalent & Alternatives

The following parts are listed as comparable options for similar system basis chip applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC33883DG	Single 5.0 V regulator (250 mA), no V2 tracking, no HS1 switch, CAN speed limited to 83.3 kbps.	Lacks peripheral supply flexibility and high-side drive; suitable only for simpler nodes without external load switching.	Select MC33883DG only if V2 tracking and HS1 functionality are unnecessary and lower CAN speed suffices.
TC358743XBG	Video bridge IC with embedded CAN controller-not an SBC; no integrated regulators, transceiver, or power management.	Designed for infotainment video routing, not power/CAN subsystem control; requires external SBC or PMIC.	Not functionally comparable; TC358743XBG serves entirely different system layer and cannot replace MC33889DDW.

Compared with MC33883DG, MC33889DDW adds V2 tracking, HS1 switching, and 125 kbps CAN-enabling richer peripheral integration and higher-speed diagnostics. Unlike TC358743XBG, it is a complete automotive SBC, eliminating need for external power and communication support ICs.

FAQ

What is the maximum CAN bus data rate supported by the MC33889DDW?

The MC33889DDW supports a maximum CAN bus data rate of 125 kbps. This is explicitly specified in the datasheet as "low-speed fault tolerant CAN interface" compliant with ISO 11898-3. The device is not rated for high-speed CAN (ISO 11898-2) operation above 125 kbps, and its loop timing (t_LOOPRD = 1.5 µs max) and slew rates (2.0–9.0 V/µs) are optimized for this speed range. MC33889DDW maintains full fault tolerance-including bus failure detection and recovery-at this rate.

Does the MC33889DDW include built-in overtemperature protection?

Yes, the MC33889DDW includes two-stage thermal protection: overtemperature prewarning (TPW) activates at 130–160 °C (setting VDDTEMP bit), and thermal shutdown (TSD) triggers at 160–190 °C. Both thresholds are guaranteed across temperature and supply conditions. The prewarning allows the host MCU to initiate thermal derating before shutdown occurs, and the shutdown is latched until VSUP drops below V_THRESH. These functions are implemented in hardware and do not require SPI configuration-MC33889DDW asserts INT and disables outputs autonomously upon TPW or TSD event.

How does the V2 regulator on the MC33889DDW differ from VDD1?

The V2 regulator on MC33889DDW is a tracking regulator controlled by the V2CTRL pin, designed to replicate VDD1's 5.0 V output using an external PNP transistor-enabling scalable current delivery beyond VDD1's 200 mA limit. Unlike VDD1 (integrated LDO), V2 requires external components (ballast transistor, capacitor network) and offers design flexibility: output voltage remains fixed at 1.0×VDD1, but current capability depends on the external PNP's gain and thermal design. V2 also features dedicated current-sense and low-voltage flags (V2LTH), allowing independent monitoring-MC33889DDW uses V2 to power peripherals while VDD1 powers the MCU core.

Can the MC33889DDW wake up from Sleep mode via the CAN bus?

Yes, the MC33889DDW can wake up from Sleep mode via the CAN bus using its TermVbat mode. In this mode, the CAN transceiver remains partially active, monitoring CANH and CANL for dominant pulses. Wake-up is triggered when a minimum dominant time (t_WAKE) of 16 µs (typical) is detected on either line-verified for MC33889D variants like MC33889DDW. The device then asserts INT and transitions to Normal mode within 40 µs (t_W-CS = 15–90 µs). This capability is hardware-implemented and does not require MCU intervention or SPI configuration prior to wake-up.

What are the key differences between MC33889DDW and MC33889BPEG?

The MC33889DDW and MC33889BPEG share identical pinout, package (28-SOICW), and core functionality but differ in CAN receiver thresholds and output drive strength. For MC33889DDW (D version), VDIFF1 min = 3.5 V (vs. 3.2 V for B), ICANH typ = 100 mA (vs. 75 mA), and ICANL typ = 140 mA (vs. 90 mA). These tighter thresholds and higher drive improve noise immunity and bus robustness in electrically harsh automotive environments. All other parameters-including VDD1 regulation, watchdog behavior, SPI timing, and power modes-are functionally identical between the two variants.
