Diodes Incorporated ZXBM5210-SP-13

Overview

ZXBM5210-SP-13 from Diodes Incorporated is a reversible DC motor driver IC with integrated full-bridge output stage, operating from 3V to 18V supply, delivering up to 1.5A typical peak output current, supporting four operational modes (Forward/Reverse/Brake/Standby), and featuring internal overcurrent, undervoltage, overvoltage, and overtemperature protection - used in 12V reversible fan and actuator control in home appliances and handheld power tools.

For engineers reviewing the ZXBM5210-SP-13 datasheet, ZXBM5210-SP-13 pinout, ZXBM5210-SP-13 application, or ZXBM5210-SP-13 equivalent, key selection considerations include its dual speed control methods (VREF voltage or external PWM), 32µA standby current, SO-8EP thermal performance, dead-time–controlled H-bridge switching, and motor-coil protection thresholds.

Technical Context

The ZXBM5210 implements a fully integrated H-bridge with complementary n- and pMOS output stages, internal PWM oscillator (20–35 kHz in VREF mode), and logic-controlled mode selection via FWD/REV pins. It uses fixed high-side + PWM-controlled low-side switching in PWM speed mode, and voltage-ratio–based duty generation in VREF mode.

Protection circuitry includes undervoltage lockout (2.6V trip, 2.8V release), overvoltage shutdown (20.7V trip, 19V release), thermal shutdown at +165°C with +25°C hysteresis, and cycle-by-cycle overcurrent detection (1.2–1.5A threshold, 10µs timeout). All protections force full output disable and automatic recovery after fault clearance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar reversible DC motor drive applications.

Compared with TB6612FNG and DRV8876N, the ZXBM5210-SP-13 offers simpler analog speed control via VREF, lower standby current (32µA vs. ≥100µA), and tighter integration for single-motor applications - but lacks current sensing or multi-channel capability.

FAQ

What speed control methods does the ZXBM5210-SP-13 support?

The ZXBM5210-SP-13 supports two independent speed control methods: (1) VREF mode, where a DC voltage (3V to VDD) applied to the VREF pin sets the internal PWM duty ratio linearly; and (2) PWM mode, where an external 20–100 kHz PWM signal applied to FWD or REV directly modulates the low-side switch. Both methods retain full direction control via FWD/REV logic levels.

How does the ZXBM5210-SP-13 handle motor braking and stopping?

In Brake mode (FWD = REV = HIGH), the ZXBM5210-SP-13 activates both low-side MOSFETs (S2 and S4), shorting the motor terminals to rapidly dissipate kinetic energy. This provides fast, controlled stopping without relying on mechanical friction or external components. The 3µs dead time prevents shoot-through during transition into Brake mode from Forward or Reverse.

What thermal performance can be expected from the SO-8EP package?

The SO-8EP package delivers 2980 mW power dissipation on a 2"×2" two-layer PCB with four thermal vias to ground flood - nearly 3× the capability of standard SO-8. At 1.5A peak current and 12V supply, junction temperature rise remains within safe limits (<+105°C ambient) when layout guidelines (exposed pad soldering, copper area, vias) are followed per Diodes' DS36765.

Is the ZXBM5210-SP-13 suitable for automotive applications?

No - the ZXBM5210-SP-13 is not AEC-Q100 qualified and is explicitly marked "NOT RECOMMENDED FOR NEW DESIGNS" in its datasheet. While it operates from -40°C to +105°C and includes robust protection features, Diodes recommends contacting their automotive team for qualified alternatives such as the AZ series motor drivers for automotive-grade deployment.
