3 / 13 page Where, Rh and Ch are the resistor and the capacitor connected to the THLD pin. If the pin is tied low, holding torque mode is disabled and normal torque prevails in both dynamic and idle motor states. DCYM, TDCYD, TDCYU DCYM and TDCYD inputs control the PWM decay modes for the LS8292 as follows: DCYM, TDCYD and TDCYU inputs control the PWM decay modes for the LS8293 as follows: Table3 DCYM TDCYD TDCYU Decay Mode 1 0 x Fast 1 1 x Slow 0 RdCd 0 Single-Mixed 0 RdCd RuCu Dual-Mixed Fast-Decay. Phase output are enabled while inhibit outputs are chopped in both dynamic and idle motor states. Slow-Decay. Inhibit output are enabled while phase outputs are chopped in both dynamic and idle motor states. Single-Mixed-Decay . Following a stepping event, if the step requires the current in a winding to decrease, fast decay is applied to the winding for a programmable duration followed by slow decay. The duration is given by: Tdcyd = 1.2 x RdCd, where Rd and Cd are the resistor and the capacitor connected to the TDCYD pin. If the step requires the current in a winding to increase, slow decay is applied to the winding. If motor is idle, slow decay is applied to both windings. Dual-Mixed-Deacy. Following a stepping event fast decay is applied to both windings for programmable durations followed by slow decay. The duration of the fast decay for the winding requiring lower current following a stepping event is given by: Tdcyd = 1.2 x RdCd and the duration of the fast decay for the winding requiring higher current following a stepping event is given by: Tdcyu = 1.2 x RuCu. Ru and Cu are the resistor and the capacitor connected to the TDCYU pin. If motor is idle, slow decay is applied to both windings. VDD Supply voltage positive terminal. DGND Supply negative terminal for digital ground. AGND Analog ground; must be connected together with DGND on the PCB.
