SYSTEM/APPLICATION INFORMATION INTRODUCTION VI/O Switching Regulator The VI/O switching regulator output voltage is determined by the MODE digital input terminals. The 34710's MODE[2:0] select the output voltage (Table 1). For example, if MODE[2:0] = 0, 0, 0, then VI/O = 5.0 V; if MODE[2:0] = Open, Open, Open, then VI/O = 3.3 V. The MODE0 terminal controls the output voltage of both regulators. The topology of the regulator is a bang-bang buck regulator operating from the internal ~200 kHz oscillator. The MODE[2:0] terminals select the output voltage as depicted in Table 1. Table 1.

VCORE Linear Regulator The VCORE linear regulator can produce a +3.3 V, 2.5 V, 1.8 V, or 1.5 V output voltage at 500 mA. The input to the VCORE regulator is a terminal that may be connected to the VI/ O regulator output. The minimum input voltage must be VCORE(NOM) + 0.8 V. 0 Open Open Open Open Open 0 0 Open Open Open indicates terminal is not connected externally. SUPERVISORY AND MISCELLANEOUS FUNCTIONS Introduction The supervisor circuitry provides control of the RST line, an open drain signal, based on system operating conditions monitored by the 34710. VI/O, VCORE, VB+, and thermal shutdown (TSD) detectors in various parts of the chip are monitored for error conditions. Because other devices in the system may trigger a reset, the RST line itself is also monitored, but the supervisor circuitry controls all reset timing, including externally generated resets. Driving the RST line low causes the system to be held in the reset state. VI/O, VCORE, VB+, and thermal shutdown have both positive- and negative-going thresholds. The supervisor circuitry also ensures that the power supplies sequence properly. Specifically, that VI/O is never less than TBD V below VCORE. This means that VCORE - VI/O will be clamped at 0.5 V, and that the VCORE regulator operation will be suppressed during startup and shutdown to ensure that VCORE - VI/O = TBD V. parameters for responding to an externally applied RST signal. The rise time may be relatively slow, depending on the load capacitance, and the internal RST input gate must operate reliably (no oscillations during the transition) under these conditions, i.e., the RST input can be inhibited for up to tphsl(MAX). Error conditions must be present for a minimum time, tfilter, before the 34710 responds to them. Once all error conditions are cleared, RST is held low for an additional time of tdelay. If any monitored item falls below its negative-going threshold for tfilter, 1.0 s to 6.0 s, the tdelay will be restarted when system operating conditions are met. The trigger for the tdelay retriggerable one shot should be ([VI/O(LOW) + VCORE(LOW) + VB+(LOW) + TJ(TSD)] & tfilter), where tfilter is the 1.0 s to 6.0 s delay. VI/O To Internal Gates From Internal Reset Circuits RPULLUP 4.7 k (Optional) RST CLOAD (Optional) Static Operating Specifications The RST output is an I/O device with an open drain output driver with a pullup and a CMOS digital input gate (Figure 3). This I/O structure allows wired OR connection to the MCU's RST I/O terminal, as well as allowing the MCU to initiate a reset cycle by driving its RST terminal low. When responding to a MCU request for a reset cycle, the 34710 must respond rapidly enough to prevent a glitch. Figure 2, page 9, shows the timing Figure 3.

Vb Charge Pump The high-side MOSFETs in the H-Bridge motor drivers and voltage regulators switch require a gate voltage in excess of VB+, which is provided by the Vb supply. The Vb regulator is a charge pump, switching directly off the VB+ supply, and uses an internal oscillator operating at 200 kHz. Internal Oscillator The internal oscillator provides timing for the charge pump and switching regulators. APPLICATIONS Power Dissipation The power budget is described in Table 2.
