SLVSFY8B February 2020 – August 2021 DRV8210
PRODUCTION DATA
The DRV8210 provides three modes to support different control schemes with the PH/IN1 and EN/IN2 pins. The MODE pin selects the control interface mode by setting it either logic low, logic high, or Hi-Z as shown in Table 8-2. The MODE pin does not latch its state, so it may be changed during operation.
The DRL package variant only supports the PWM interface (see Table 8-3).
MODE STATE | CONTROL MODE |
---|---|
MODE = Logic Low | PWM |
MODE = Logic High | PH/EN |
MODE = Hi-Z | Half-Bridge |
The inputs can accept DC or pulse-width modulated (PWM) voltage signals with duty cycles from 0% to 100%. By default, the INx, PH/IN1, and EN/IN2 pins have internal pulldown resistors to ensure the outputs are Hi-Z if no inputs are present (the only exception is half-bridge mode, where OUTx = L if INx is floating).
The following sections show the truth tables for each control mode. Additionally, the DRV8210 automatically handles the dead-time generation when switching between the high-side and low-side MOSFET of a half-bridge. Figure 8-3 describes the naming and configuration for the various H-bridge states described in the following sections.
