ZHCSO45 October 2021 TCAN1044AEV-Q1

PRODUCTION DATA

The TCAN1044AEV-Q1 logic I/Os support CMOS levels with respect to V_IO for compatibility with MCUs that support 1.8-V, 2.5-V, 3.3-V, or 5-V systems.

Table 8-4 Driver Function Table

Device Mode	TXD Input⁽²⁾	Bus Outputs		Driven Bus State⁽²⁾
Device Mode	TXD Input⁽²⁾	CANH	CANL	Driven Bus State⁽²⁾
Normal	Low	High	Low	Dominant
Normal	High or open	High impedance	High impedance	Biased recessive
Standby	X	High impedance	High impedance	Biased to ground

(2) X = irrelevant

(2) For bus state and bias see Figure 8-2 and Figure 8-3

Table 8-5 Receiver Function Table Normal and Standby Mode

Device Mode	CAN Differential Inputs V_ID = V_CANH – V_CANL	Bus State	RXD Pin
Normal	V_ID ≥ 0.9 V	Dominant	Low
	0.5 V < V_ID < 0.9 V	Undefined	Undefined
	V_ID ≤ 0.5 V	Recessive	High
Standby	V_ID ≥ 1.15 V	Dominant	High Low if a remote wake event occurred See Figure 8-5
	0.4 V < V_ID < 1.15 V	Undefined
	V_ID ≤ 0.4 V	Recessive
Any	Open (V_ID ≈ 0 V)	Open	High
