NXP Semiconductors MPC17511EV

Overview

MPC17511EV from NXP Semiconductors (formerly Freescale) is a monolithic H-bridge motor driver IC designed for bidirectional control of micro brushed DC motors in portable battery-powered systems. It delivers 1.0 A continuous / 3.0 A peak output current, supports 2.0–6.8 V motor supply, features 0.46 Ω typical R_DS(ON), integrated charge pump, shoot-through protection, and operates up to 200 kHz PWM - enabling precise speed/torque control in optical disc drives and SLR camera focus mechanisms.

For engineers reviewing the MPC17511EV datasheet, MPC17511EV pinout, MPC17511EV application, or MPC17511EV equivalent, key selection considerations include its 16-pin VMFP package, tri-state bridge control mode, TSWITCH output for external MOSFET drive, undervoltage lockout, and compatibility with 2.7–5.7 V logic interfaces in space-constrained portable designs.

Technical Context

The MPC17511EV implements a fully integrated dual-channel gate driver with internal charge pump and level shifter to enable high-side NMOS switching without external bootstrap components. Its four-mode control logic (Forward, Reverse, Brake, Tri-state) is decoded directly from parallel IN1/IN2/IN3 inputs, independent of PWM timing.

It integrates undervoltage detection on VM (2.0 V threshold), shoot-through prevention via hardware interlock between high- and low-side drivers, and thermal shutdown. The TSWITCH output provides open-drain control signal synchronized with bridge state transitions for driving an external high-current MOSFET in hybrid motor drive configurations.

FAQ

What is the maximum continuous motor current supported by the MPC17511EV?

The MPC17511EV supports 1.0 A continuous output current per channel under typical thermal conditions (T_A ≤ 65°C, proper PCB copper pour). This rating assumes use of the exposed thermal pad and recommended layout per Freescale AN1085. Peak current capability is 3.0 A for short durations, limited by internal thermal shutdown. Exceeding 1.0 A continuously without enhanced cooling will trigger thermal protection in the MPC17511EV.

Does the MPC17511EV require external components for high-side drive?

No, the MPC17511EV integrates a charge pump and level shifter to generate sufficient gate voltage for internal high-side NMOS transistors. Only a single 100 nF ceramic capacitor on the CRES pin is required. This eliminates external bootstrap diodes and capacitors, simplifying design and reducing bill-of-materials count for the MPC17511EV compared to discrete H-bridge solutions.

What logic voltage levels are compatible with the MPC17511EV inputs?

The MPC17511EV accepts logic inputs from 2.7 V to 5.7 V, making it compatible with both 3.3 V and 5.0 V microcontrollers without level translation. The IN1, IN2, IN3, and EN pins are all referenced to VDD, and the device guarantees correct decoding across this full range. This dual-voltage compatibility is explicitly verified in the MPC17511EV datasheet Rev. 1 test conditions.

How does the TSWITCH output function in the MPC17511EV?

The TSWITCH output is an open-drain signal synchronized with the internal H-bridge state transitions. When the bridge is active (Forward/Reverse/Brake), TSWITCH pulls low; during Tri-state (open), it floats high. This allows direct connection to the gate of an external N-channel MOSFET to extend current capacity beyond the MPC17511EV's 3.0 A peak rating in hybrid motor drive topologies.

Is undervoltage protection active on both VDD and VM supplies in the MPC17511EV?

Undervoltage lockout (UVLO) in the MPC17511EV is implemented only on the VM supply pin, with a fixed 2.0 V threshold. VDD has no UVLO circuit - logic functionality ceases only if VDD drops below the minimum specified 2.7 V, but no automatic shutdown is triggered. The VM UVLO ensures motor operation halts safely before battery depletion causes erratic behavior, a key reliability feature of the MPC17511EV.
