PARAMETER DESCRIPTION MIN MAX UNIT RST10 tw(WARMRSTnL) (1) Pulse Width minimum, WARMRSTn active (low) 500 16384000 ns (1) This timing parameter is controlled by the TOP_RCM.WARM_RSTTIME1/2/3 registers. See the Reset section of the Technical Reference Manual for more details. WARMRSTn RST10 Figure 6-6. WARMRSTn Timing Requirements and Switching Characteristics 6.11.3.3 Safety Signal Timing Tables and figures provided in this section define switching characteristics for SAFETY_ERRORn. 6.11.3.3.1 SAFETY_ERRORn Switching Characteristics NO. PARAMETER DESCRIPTION MIN MAX UNIT SFTY1 tc(SAFETY_ERRORn) Cycle time minimum, SAFETY_ERRORn (PWM mode enabled) (P(1) × H(3)) + (P(1) × L)(4) ns SFTY2 tw(SAFETY_ERRORn) Pulse width minimum, SAFETY_ERRORn active (PWM mode disabled)(5) P(1) × R(2) ns SFTY3 td(ERROR_CONDITIO N-SAFETY_ERRORnL) Delay time, ERROR_CONDITION to SAFETY_ERRORn active(5) 50 × P(1) ns (1) P = ESM functional clock (2) R = Error Pin Counter Pre-Load Register count value (3) H = Error Pin PWM High Pre-Load Register count value (4) L = Error Pin PWM Low Pre-Load Register count value (5) When PWM mode is enabled, SAFETY_ERRORn stops toggling after SFTY3 and will maintain its value (either high or low) until the error is cleared. When PWM mode is disabled, SAFETY_ERRORn is active low www.ti.com AM2612, AM2611, AM2611-Q1, AM2612-Q1 SPRSPA7C – SEPTEMBER 2024 – REVISED JULY 2025 Copyright © 2025 Texas Instruments Incorporated Submit Document Feedback 107 Product Folder Links: AM2612 AM2611 AM2611-Q1 AM2612-Q1 |
