Product details

Overview

ZXBM5408Q-S14-13 from Diodes Incorporated is an AEC-Q100 Grade 1 qualified brushed DC motor driver IC with integrated H-bridge, servo control logic, and comprehensive fault protection. It delivers 0.8A continuous / 1.5A peak drive current across 8V–18V supply, supports programmable hysteresis and deadband via external resistors, and is designed for automotive headlight position control and industrial servo systems.

For engineers reviewing the ZXBM5408Q-S14-13 datasheet, ZXBM5408Q-S14-13 pinout, ZXBM5408Q-S14-13 application, or ZXBM5408Q-S14-13 equivalent, this device provides verified servo feedback handling (FB/REF), RANGE input fault detection, thermal shutdown at +170°C, and SO-14 package compatibility with automotive PPAP support.

Technical Context

The ZXBM5408Q integrates a full-bridge power stage with low-R_DS(on) MOSFETs (typ. 1.8Ω total path) and analog servo control blocks-including position feedback amplifier, range monitor comparator, hysteresis window generator, and deadband logic-all operating from a single 8–18V rail. Its servo loop responds to differential voltage between FB and REF pins, with rotation direction determined by V_FB relative to V_REF, hysteresis thresholds (±2% of V_DD), and deadband width (0.4–1.2% of V_DD).

Fault management is hardware-based and autonomous: RANGE pin monitors open/short conditions using dual thresholds (VOFFL = 300–500mV, VOFFH = –100 to +150mV referenced to GND/VDD); UVLO activates at 6.3–6.9V (shutdown) and releases at 7.4–8V; OVP triggers at 18.5–23V and recovers at 17.5–22V; overcurrent trips at ≥1.5A for >4µs, initiating 260µs retry cycles.

Key Specifications

Pinout & Package

Package: SO-14 (Type A1), surface-mount, RoHS-compliant, matte tin-plated leads, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
1 FB	Position Feedback Input	Voltage input referenced to GND; compares against REF to determine motor direction and brake state.
2 HYST	Hysteresis Control I/O	Analog input setting hysteresis window center and width; bias current ±0.35µA enables resistor-programmable thresholds.
3 NC	No Connection	Unbonded die pad; must remain unconnected per datasheet layout guidance.
4 GND	Ground Reference	Main power and signal ground; four dedicated pins (4,5,10,11) ensure low-impedance return path for motor current and analog circuitry.
5 GND	Ground Reference	Second dedicated ground pin-critical for noise immunity in servo feedback path.
6 OUT1	H-Bridge Output 1	High-side/low-side switch node; drives one terminal of DC motor coil in conjunction with OUT2.
7 NC	No Connection	Unbonded; no internal connection-leave floating or tie to GND only if required by PCB routing.
8 VDD	Power Supply Input	Primary 8–18V supply input; requires local 100nF ceramic decoupling (C1) placed adjacent to pin.
9 OUT2	H-Bridge Output 2	Complementary H-bridge output; phase inversion relative to OUT1 enables bidirectional motor control.
10 GND	Ground Reference	Third ground pin-supports thermal dissipation and reduces ground bounce during switching transitions.
11 GND	Ground Reference	Fourth ground pin-ensures stable reference for RANGE, REF, and FB analog comparators.
12 NC	No Connection	Unbonded; no internal function-do not connect.
13 RANGE	Fault Monitoring Input	Input for potentiometer wiper; monitored by dual-threshold comparator to disable outputs on open/short faults.
14 REF	Reference Input	Servo setpoint voltage input; differential comparison with FB determines CW/CCW/brake states.

Equivalent & Alternatives

The following parts are listed as comparable options for similar brushed DC servo motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TB9051FTG	3-phase BLDC driver with integrated FETs; requires external position sensing (Hall/encoder); no native FB/REF servo loop.	Designed for brushless motors in EPS systems; lacks analog servo inputs and RANGE fault monitoring.	Select only when upgrading from brushed to BLDC motors and adding position sensor infrastructure.
DRV8876N	H-bridge with 3.6A peak current, SPI configuration, and current sense output; no built-in hysteresis/deadband or RANGE comparator.	Targets high-current industrial actuators; requires MCU for servo logic and fault interpretation.	Choose when digital control, current monitoring, or higher drive strength (>0.8A continuous) is mandatory.

Compared with TB9051FTG and DRV8876N, the ZXBM5408Q-S14-13 uniquely integrates analog servo control, RANGE fault detection, and automotive qualification in a single SO-14 package-reducing design effort for cost-sensitive, MCU-less headlight and valve positioning systems.

FAQ

What is the maximum allowable voltage on the RANGE pin?

The RANGE pin supports voltages from –0.3V to +20V absolute maximum. Its internal comparator monitors for open-circuit (VOFFH ≈ VDD +150mV) and short-to-ground (VOFFL = 300–500mV) conditions. Exceeding 20V risks permanent damage; operation above VDD by more than 150mV triggers immediate motor shutdown.

Can the ZXBM5408Q-S14-13 drive a 24V motor?

No. The recommended operating supply voltage is strictly 8V to 18V. While the absolute maximum VDD rating is 45V (transient only), sustained operation above 18V violates functional specifications: OVP triggers at 18.5–23V, and internal references (REF/FB quiescent voltage = 185–215mV) are calibrated for 8–18V rails. Use only within specified range.

How does the HYST pin affect motor behavior?

The HYST pin sets the hysteresis window (3–5% of VDD) that defines the voltage band around the REF setpoint where the motor remains stationary. Increasing hysteresis width prevents chatter near position targets but reduces positioning resolution; decreasing it improves accuracy but risks oscillation. Configuration uses two external resistors (RHYH/RHYL) per datasheet Figure 1.

Is external current sensing required for overcurrent protection?

No. Overcurrent protection is fully internal and automatic: the device monitors total bridge current and shuts down both outputs for 260µs if ≥1.5A is detected for >4µs. No external sense resistor, amplifier, or MCU polling is needed-the protection activates independently of system control logic.
